Save Big On 6L6GC-STR Tung-Sol reissue Tubes!! These are the same as the tubes listed inthe power tube section

and ready to use - I have good stock on hand. Just $17.50 ea., $35.50/pair, $71.50/quad.

my price is $3.00. Handy to have around - decent sounding too!
Rare Tubes! (11) 12AT7 GE, NOS tubes from the late 1950s, all are grey plates with rectangular getters. All have been run in
and carefully tested - including testing for low noise and microphonics. I have (8) single tubes, all test good but have not quiet enough for low
noise applications. They may have some minor getter rainbowing, These would be fine tubes for a power amp or line stage, $16.50 ea.

(2 pairs & 2 singles) JTL-6AQ5 Tung-Sol, used but test new or very close to it; all have plenty of getter left. These
would excel in a Duttman/McShane "El-Cheapo" amp or a DIY project. Remember, the 6AQ5 is electrically almost
identical to the 6V6 (be nice to the 'AQ screens).They're great tubes at a nice price - $18.50/pair, $8.50 ea for singles.
(1) JRC-6005/6AQ5W RCA black plates, great little 6AQ5 "premium" sub. These came in a bulk styrofoam
container, so it is white boxed. $9.50.

(1) 6AS7G branded Amperex but really Russian made, new in white box, $9.50.

Genalex Gold Lion N709/EL84 reissues! I now keep a good supply of these very well made tubes in stock. Construction
quality is superb, and the performance on the test bench looks great. The reviews are very positive as well! Clearly this is the
best new production EL84 in production now. They are $29.50 ea., $59.95/pair, $119.50/quad - and I match EVERY one
personally (not the poor/inconsistent "factory" match)!
Important! N709 tubes are not guaranteed if installed in a Vox AC-30 or an AC-30 clone. These amps
run them at at nearly 15 watts plate dissipation - the tube is rated at 12 watts. Please also note that MANY
(most?) vintage audio and guitar amps run EL-84 tubes beyond their ratings! The tubes will fail quickly,
and this failure is not warranteed, sorry.
(2) EL84/6BQ5 RCA NOS/NIB grey plate tubes - 6.8 ma apart in current so may not be usable as a pair. Excellent crisp boxes,
really fine late 60s-early 70s tubes, $39.50 ea.

6CA7 Electro-Harmonix "fat boys" - a true 6CA7, very well regarded. Pairs/quads are matched properly by me personally, and that
means it's done right! Excellent choice for audio gear, $21.50 ea. for singles, $44.50 per matched pair, $89.50 for a matched quad.
(1) 6CD6GA RCA, new in white box, $6.50 (more on hand awaiting testing, inquire if you're interested).(3) 6CM5/EL36, 2 Mullard branded Rogers Canada, NOS/NIB, $29.50 ea. One RFT branded United,
(20+) 6CM6 USA made, NOS & most in original boxes, $6.50 ea., $14.50/pair if available. Great tubes for "El-Cheapo" amp!
(4) 6CW5/EL86, all used, all test very good to near new, two European Philips (Mullard, Mazda) for $9.50 each; two USA/Canada for $5.50 each.
(6) 6CZ5, three NOS & two ANOS, various brands, some in original box, these are an excelent choice to sub for the pricey and scarce 6973 tube
used in jukeboxes and other gear. Even the 6CZ5s are drying up, the next choice for an old stock sub is a 6CM6 (it will take a bit of socket rewiring).
$13.50 ea. for new, $11.50 ea. for ANOS

7591A Electro-Harmonix tubes in stock! $21.50 each single, $44.50/matched pair, and $89.50/quad. Here's a typical customer comment...
"I put the EH 7591's in my Pilot SA-264 power amp. Set the bias and let 'em cook a while. Then I listened. I was really surprised.
They sound like the real thing. What a sweet sounding amp that is." They sound like it because they are the real thing, just in a larger bottle!
Please note - I have just a few singles left and once they are gone I will not be stocking/selling the 7591A EH for the
foreseeable future due to the complexity of installing them in so many of the vintage amps.
7591A Tung-Sol - some stock on hand and more will be in stock soon. This is the only 7591A or 7868 tube that
I'll be handling at this time. $34.50 each, $69.50/matched pair, $139.50/matched quad
Important note - updated! There have been some cases where the new production 7591A (and 7868) tubes have had trouble
in circuits using a very high value grid resistor - as vintage Scotts, Fishers, and others sometimes do. The best solution is changing
all the grid resistors to 200K-220K from the original value, since often the factory spec resistors exceeded the maximum
recommendations. For instance, Fisher routinely used 330K carbon resistors that would often drift up to 360K over time! As well,
to prevent loss of deep bass energy a change of the output coupling cap value to .1 uf (preferred) is needed. I stock all the parts
you need, the parts cost is only $15.00 to $30.00 per amp, depending on the coupling cap you prefer to use. As well, many amps
will require adjustable bias to be installed to accommmodate the available tubes.
I do not recommend the use of JJ tubes under any circumstances, not even with the changes above!
Click here for a look at a typical 7591 output circuit. Resistors R129 & R130 and caps C87 & C88 in the outlined
boxes are what may need replacement.
7695 Sylvania branded GE, NOS/NIB, these are 50 volt beam power tubes, $12.50.
7868 Electro Harmonix, Sorry! I am no longer handling the 7868 tubes. It is just too much trouble and there are too
many issues involved in handling them due to the complexity of installing them in so many of the vintage amps.
(1) 8552 RCA, NOS but came in a Motorola box, it's a 12 volt 6146 (same tube as 6883B), $17.50.
*EL34 Electro-Harmonix tubes. A very nice skinny bottle tube with a lively top end, and they are priced very
reasonably at $15.50 ea., $31.50/pair, $63.50/quad.
(2) EL34 Matsushita (Japanese made, branded RCA), one probably NOS/NIB (marked "made in Great Britain") one used.
The NOS tube is a cool biasing tube, it tests strong and looks good with just a couple minor base scratches, $59.50. The second
is used/white boxed and tests near new - but the getter is worn to the size of a US nickel, $21.50.
Mullard reissue EL34 tubes. These were modeled after the xf4, and the people who've heard
the tube like it a lot!

Genalex Gold Lion KT-66 They look good, they are rock solid on the the burn-in/match rig, reviews are superb, the sonics are amazing.
This tube is a hit! Do be aware they draw about .3 amps per tube more heater current than a 6L6, so be sure your amp can supply it safely
before you plug them in. Otherwise they are a drop in replacment for the 6L6. $39.50 for singles, $79.50/pair, or $159.50 for a quad.
Genalex Gold Lion KT-77 reissues! I now have a good supply of these really great sounding & well made tubes in stock. Unlike the other
KT-77 brand in the market, these tubes are rock solid quality and reliability is excellent! Singles are $46.50, pairs are $94.50, quads are $189.50.
Genalex Gold Lion KT-88 reissues - good stock on hand! The listening reports are virtually unanimous, regardless of what gear the tubes go in.Raytheon
This tube is clearly the equal of and according to many are even be better than the original GEC. It is absolutely the best on the market now!
My impressions from handling and matching the tubes are extremely positive. The tube is very substantial in your hand, they feel heavy and look well made.
This is the tube we use and recommend for the demanding Harman-Kardon Citation II amp. Singles are $61.50, matched pairs are $124.50,
matched quads are $249.50; octets (when available) are $499.50.
KT-88 Electro-Harmonix . This tube has 90% of the performance of the very best KT-88s at 1/2 the price! Very tight bass (I wish there
was a tad more of it though), beautiful mids and highs - and a tough, reliable tube too. Only $37.50 ea., $76.50/pair, $154.50/quad.
KT-90 Electro-Harmonix (EH). I now find that these recent production EH are much better performers both on the test
bench and in listening reports. I now keep a good stock on hand - matched right by me personally! Singles are $44.50 ea., pairs are $89.50, quads are $179.50.
KT-120 Tung-Sol. Rugged power tubes with significantly higher dissipation limits than the KT-88 or KT-90 carry; I am
now keeping good stock on hand - matched right by me personally! Note - these tubes require .2 to .3 amps more heater current
than KT-88s, so check and be sure your amp can handle them!! Singles are $49.50 ea, pairs are $99.50, quads are $199.50.

6CG7 Electro-Harmonix; the NOS supply is getting really thin - especially if you wanted multiple identical tubes or a matched pair - so

$4.00 or $5.00 extra for from some other vendors!
6CG7 Electro-Harmonix Gold; in vintage gear (where most 6CG7/6FQ7s are found!) the added thickness and enhanced contact of

piece of vintage gear, or simply want to have the best possible contact with your sockets grab this tube! $25.50 ea. or $52.50 for a

of any of the 6922 types out there today. This is the only tube I'll send for use in AI, ARC and a few
other brands. And yes, a large number of my customers say they like the sound too! Only $16.50 ea. single.
$33.50 for gain matched pairs, and $35.50 for pairs of gain matched tubes with balanced cathode sections.
Genalex Gold Lion E88CC/6922 - in stock! Read this customer report: "I installed the 6922s in my Blue Circle BC-24
hybrid amp a week ago when they arrived. As I put more hours on them, the bass has lessened and the tubes became
more balanced, yet retained their smooth character. After a week's worth of playing, I'd say that they are quite extended
without being bright, punchy without being bass heavy, detailed without etch, and ever so slightly warm without being sluggish.
Oh, and the midrange is excellent! Finally! A premium 6922, every bit as good as the best NOS - at a fraction of NOS prices!
$44.50 ea., $89.50/matched pair, $92.50/matched pair with balanced triodes.
For the "finicky" gear out there you can request my Genalex"Select Grade" 6922. These tubes are tested for:
Plate current/DC balance(twice!)
AC balance/section balance (twice!)
Grid current ("gas")
In addition, these tubes receive a special run-in before testing, and are the best of the type out there.
Special testing like this takes time but if you have a fussy amp this test regimen may be your only chance to get the
tubes you need. DON'T REQUEST THESE UNLESS YOU NEED THEM! You are just wasting your money and
making it harder to supply these to people who do need them. $59.50 ea. or $122.50/matched pair when available.

12AT7 and Equivalent Types...
Very Important Note! The only tube I recommend (or guarantee) as a reverb driver in guitar amps is the
JAN Philips 12AT7WC. If you want to try something else feel free - but you do so at your own risk!
(1) 12AT7 GE, NOS branded Philco in old Philco box, date coded 35th week of 1951, one of the oldest
12AT7s I've seen. Grey plate, square getter, a rare tube! $29.50.
(2) 6679/12AT7 GE, one NOS/NIB, $18.50; one ANOS square getter, $13.50.
(3) JG-12AT7 GE 1954 military stock, 2 NOS in the military packaging & one ANOS, grey plate square getter
tubes. Two nice NOS singles for $24.50 ea., one ANOS for $18.50.
(58) CV4024/12AT7 Mullard, NOS/NIB, military boxed, the pin protectors in place, no Mullard logo on
them. With double stapled plates and copper getter ring supports, these are really fine tubes, $44.50 ea., $89.50/pair.
Beware of fakes!! A number of vendors have used/washed tubes in fake boxes and are selling them for full price! In
their defense, they may not even know they have used tubes! But I guarantee my stock is 100% new!
(3) 12AT7 RCA, may be new but ??, some white boxed, $19.50 ea.
(1) 12AT7 RCA, ANOS, branded CBS/Hytron, black plate square getter 1955 tube, $19.50.
(2) 6679/12AT7 RCA, maybe not new but close, white boxed, $21.50 ea.
(1) 12AT7 RCA, NOS in old distributor box, black plate, square getter 1962 tube. This tube
may be too microphonic for use except as an RF tube, so steal it for $11.50.
(1) ECC81/12AT7 Siemens, double mica, NOS/NIB branded ITT. Low noise/microphonics, $44.50.
(26) 12AT7WC Philips JAN, NIB, $14.50 ea., $29.50/pair. Excellent Fender reverb driver tube, not my favorite audio tube. Good stock on hand!!

(10+) 12AU6, good US & Japanese brands, new, may be white boxed, 12 volt version of the 6AU6, $3.50 ea.
12AU7 and Equivalent Types...
Genalex Gold Lion B749/ECC82/12AU7 reissues This tube has warmth and body, the noise level is very low, and microphonics
are virtually nonexistent. The track record is clear - these Genalex reissue tubes are superb, as good as most of the old stock! $44.50 ea., $89.50/pair.
(1) 12AU7A GE, good used D-getter tube with horizontal rib plate and good gain/Gm match, $9.50.
(1) 12AU7A Raytheon USA, NOS/NIB 1950s tube; black plate round getter tube, a bit too noisy
for use in low level sockets but perfect for line/amp level. $37.50.
(1) 12AU7A Raytheon USA, white boxed; grey plate square getter tube, ANOS for $24.50.
(1) JRC-12AU7 RCA, 1950s production, grey plate/top getter, NOS in an original (but I think wrong) box, $29.50.(4) ECC82/12AU7 RFT NOS in white boxes, all are low noise/microphonics and have balanced triode sections; very nice tubes! $29.50 ea.
12AU7W/6189 Tung-Sol new production tubes, excellent quality and tone, a very pleasant surprise! This tube is a really good choice and
at nice prices too! $21.50 each, $44.50/pair. Remember, my price includes a lot of tests other vendors charge extra for!
(1) 12AU7/A Tung-Sol, NOS/NIB round getter - early '60s(?), low microphonics & noise, $39.50.
(2) 12AU7/A Tung-Sol, 1 12AU7 used/tests about 150% of minimum, "D" getter grey plate, nice tube, $19.50.
The second (12AU7A) tests within 10% of new, is also a "D" getter grey plate, $29.50; the third is branded Delco,
is a nice ANOS tube, $34.50.
(1) 12AU7 Tung-Sol, used/tests about 125% of minimum, black large plate, nice looking tube, $16.50
(6) 12AU7A Tung-Sol, various brand markings, clear glass/grey plates, may be new, but ??, white boxed,
very nice tubes! $28.50 ea.
(1) 5814 GE, ANOS grey plate with triangle markings, pizza pan getter and extra supports, $15.50.
(1) 5814A Sylvania (not Philips) JAN, 1968 production grey plate NOS/NIB, $19.50.
(1) 5963 GE, NOS/NIB, crisp original box, low microphonics! $12.50.
(3) 5963 RCA, grey plate & round getter, in old industrial box or a white boxes, almost surely NOS, $16.50 ea.
(1) 5963 RCA, grey plate/square getter, in a white box, call them "ANOS", $17.50.
(1) 5963 RCA, as above but in the original RCA box, slightly microphonic, an o-ring damper cleans
it up, excellent for line stages or power amps, $8.50.
(20+) 12AV7, medium mu dual triode, about the same mu as 12AY7, cheap too. These use the same pinout as the rest
of 12**7 family. Try 'em, you'll be surprised, $6.50 ea., black plates $7.50 ea.
(1) 5965 RCA 3 mica, maybe new but ??, good gain and Gm match, low microphonics and noise (!), good section
balance, nice tube in a white box, $13.50.
(1) 5965 GE, ANOS large grey plate tube in a white box, branded Beckman, $6.50.
12AX7/ECC83 and Equivalent Types... note that the 5751 can be used as a sub in many cases, but it has a
lower mu specification - 70 for the 5751, 100 for the 12AX7. I don't recommend it as a sub in phono stages.
Also all my 12AX7s are noise tested - many other places charge extra for that testing!
Genalex Gold Lion B759/ECC83/12AX7 reissues! Tis is a great tube - warm, excellent (one customer described it
as "sublime!") midrange and super soundstaging. The latest production tubes are much quieter, I can now recommend it for
phono and or other noise sensitive stages with its low hum spiral wound heater. $44.50 ea., $89.50/pair.
Mullard reissue 12AX7 long plates! Another new production tube getting excellent reviews! One more fine quality
tube, and just $18.50 ea. or $39.50/pair. As usual, my price includes tests you pay extra for from some other vendors! I have
good stock on hand, ready to ship!
Mullard reissue CV4004/12AX7 short plates! Initial reports are quite positive and based on what I've seen from
the Mullard reissue line so far I expect it to be an excellent tube - and more microphonics resistant due to the tube's short
plates (as compared to the long plate Mullard). Be sure to order the CV4004 if you want the short plate tube! If
you order the 12AX7 you'll get a long plate! $21.50 ea., $43.50/matched pair.
*Sovtek 12AX7LPS tubes, very low noise spiral filaments, checked for good section-to-section match, $17.75 ea.,
or $36.75 per matched pair; quads (if available - these are VERY rarely needed) are $74.50. For specially selected tubes
(for Aesthetix and other hi gain/noise sensitive gear) selected pairs (when available) are $59.50. These are great for sockets
where a good quiet tube is needed, and the tone is top shelf. My tube of choice for Citation phono stages!
12AX7 Tung-Sol reissue. Many very good reports are coming in on this tube! It's punchy, has extended treble and
excellent bass, and is nice and quiet. $18.50 ea.; matched pairs are $37.50/pair.
12AX7/ECC803S Tung-Sol gold pin. Get improved socket contact with this tube. If you have any wear on the socket
the extra thickness of the plating and the corrosion resistance and good connectivity of the gold pins can help. $32.50 ea.,
matched pairs are $65.50/pair.
5751 Tung-Sol reissue; these have received many very positive reviews and they test VERY quiet!
The NOS is about gone - especially if you need matched tubes - so here's a terrific new 5751 at a great price, $24.50 ea.
or $49.50/matched pair. Remember, my price includes testing others don't do or you pay extra for!!
Rare Tubes! 12AY7 GE, NOS tubes from the late 1950s to 1960 or so, all are grey plates, most with rectangular getters. All have been
run in and carefully tested - including testing for low noise and microphonics. Here's what I have:
(2) matched/balanced very low noise pairs with round getters and grey plates - $79.50/pair
(5) single tubes with good internal section match and low noise, $34.50 ea.
(3) single tubes, all test good but not quiet enough for low noise applications. These would be fine in a power amp or line stage, $29.50 ea.
(1) 12AY7 RCA, NOS/NIB grey plates, it has balanced sections and low microphonics but may be to noisy for any use but line level, $29.50.Great Tube! 12AY7/6072 EH Gold; just like with the 5751 the NOS supply is about gone, and what's left isgetting very pricey. The gold-pinned EH
Keep in mind my price includes testing others don't do - or you pay extra for!!
Update on the EH 6072 - I have used these in my "McShane" amp - and they were outstanding!! They replaced
some CV4024 Mullards, and they were every bit as good. Quiet, great tone, a big-time winner!
(1) 12AZ7 RCA, NOS/NIB black plate/square getter tube; matched balanced very low noise, $19.50.
12BH7 Electro-Harmonix; the NOS supply is getting so thin that I decided it was time to bring in yet
another excellent quality EH tube. Nice section match, low noise, a very fine tube. Just $18.50 ea. or $39.50 for
a matched pair. Don't forget - my price includes testing you pay $4.00 or $5.00 extra for from some other vendors!
12BH7 Electro-Harmonix Gold; especially in vintage gear I've found the added thickness and enhanced contact of
the gold plated pins makes a real difference in the quality of the pin-to-socket contact. So if you do a lot of tube rolling,
have a piece of vintage gear, or simply want to have the best possible contact with your sockets grab this tube! $26.50 ea.
or $54.50 for a matched pair. Again, my price includes testing you pay $4.00 or $5.00 extra for from some other vendors!
Note: Tubes specially tested/selected for Citation current source kits are $19.50 ea. (CCS not available as a kit - installed by us only).
(26) 12BY7/A RCA, many are all different construction though, so don't wait if you want identical tubes. $19.50 ea. A few nice used are available for $9.50 ea.
(Over 40 on hand!) 12BY7/A, other USA brands, many older Sylvania, many nice GE, $22.50 ea. Almost new examples are available for $9.50 ea.
(20) 12BY7A NOS made in Japan, branded Channel Master, Raytheon, etc. New tubes - great price, $13.50 ea.
Good used tested 12BY7A are available for only $5.50 ea.
(1) 12BZ7; (1) Marconi/Radiotron NOS/NIB, for power amps only, a bit too noisy for other uses, $7.50.
(14) 12GN7, super high Gm pentode, very similar & pin compatible to a 12BY7A. Recommended by Alan Kimmel as
a top tube in a mu-stage. New tubes from good makers, $7.50 ea. A few good used for $4.00 ea.
(2) 12J5GT Tung-Sol, NOS/NIB, 60s vintage grey plates, $7.50 ea.
(10) 12SL7, mostly Sylvania, new, nice stuff, a few are white boxed, $7.50 ea. ($9.50 for RCA).
(1) 12SQ7GT Sylvania, rare glass/metal based version of this tube, ANOS, $7.50.
(6) CK-5670 NOS Raytheon USA early 1960s vintage black plate tube, fine tubes! $24.50 each
(1) JG-5670 GE 1960 black plate 3 mica tube, may be new but ??, $34.50 each
(2) 5670W/2C51, GE JAN black plate NOS/NIB, very nice sub for the 6N3 in Shanling CD players
and other Chinese gear. Check out this recent note I received: "I rec'd the 5670W from you a month ago,
but I didnt have time to try them out until now. Just want to let you know that they are FAR FAR superior
than the chinese 6N3 which came with my amp. The difference is so great that it is not even funny, its
saddening. I nearly sold my 2A3 amplifier because of those crappy chinese tubes. The 5670 is simply
6x or 10x better." Heck, a number of my customers actually prefer these to the rare and pricey 396A!
Try 'em! $12.50 ea.
(1) 5687, GE 5 Star black plate NOS, 1959/1960 era vintage, Amplitex tested, outstanding tube! $29.50
(26) 5687WA or WB Philips or Sylvania branded, NOS, a few older white boxed tubes, and many JAN or CHS
designated. Black vertical rib plates, good stuff! $32.50 ea. for 1980s vintage, $39.50 ea. for earlier production. I'll be
sure to send as close to identical tubes as I can if you want more than one.

Tube shipping is usually $8.50 to any USA address (up to 2 pounds. Shipments to Canada up to 1-2 pounds are about
$18.50 - $36.50 as well. I'm located in Orland Park, IL, just outside Chicago.
"Received the valves today, installed them this evening, simply fantastic. I must add my sincere appreciation for the
superb service level provided by yourself." Enzo, from Australia.
I had received my 10mar05 tube order no more than 2 days after your receipt of my payment and
I can say that your matched sets are prime (you must listen to a lot of tubes pop as they hit the
bottom of your trash can)! I wanted to say that I will be a return customer. D. Dwyer, USA.
Guarantees and Returns!
All new or new old stock tubes and/or parts are guaranteed for 90 days from the date of purchase. ANOS or used
tubes are guaranteed for 30 days. A few tubes have different warranty periods, those will be listed on my site or below.
Tubes/parts that have been been misused or installed in sockets designed for a different tube are not warrantable.
Defective tubes or parts must be returned for evaluation; if found to be defective they will either be replaced or a
credit issued (my choice). Tubes must be returned in the same condition as when received, with all packaging present
and in original condition. Items cut to length cannot be returned (except if shipped in error). For purchasers outside
the USA - you are responsible for shipping the defective item back to me at your expense as well as for the return
shipping of the replacement part back to you. I will give you a $8.50 discount on the return shipping. If this is not
clear please email me with your questions!
Tubes may be returned only if defective. Note that most tubes returned to me are NOT defective, but have either
been damaged in use or had poor contact with the tube socket - or were installed in an improperly biased power
amplifier. Bias procedures for Citation tube amps can be found on this site, for other amps please consult the
manufacturer's data or a qualified technician. Failures caused by operating tubes beyond their dissipation limits is
not covered by the warranty, sorry.
Please note! Tubes used in Audio Research (ARC) gear other than the original equipment brand and number
(with the exception of substituting EH for Sovtek tubes) may be warranteed not to be DOA only. There is no other
warranty whatsoever - check on the specific tube when you order if you wish. Original equipment brand and
number tubes carry the normal warranty described above.
While I strive to give the best advice I can regarding what tubes are best sounding for a given application, each
system and listener is different. It simply isn't possible to guarantee the tone will be exactly what the purchaser
expects. I cannot sell tubes "to try out" or for "auditions" without significantly increasing my prices, which I
don't want to do. I cannot accept returns of tubes you bought for an amp that was later sold/gave away, decided
not to use, etc.
At my option, I may offer to repurchase the tubes at a mutually agreed upon price, but there is no obligation on
my part to do so.
This warranty covers only the tubes and parts purchased from me, and is limited to replacement (or refund) for
that specific item. Resultant damage to equipment is specifically NOT covered.
To request a return please email a description of the problem and the date of purchase. I'll reply ASAP with
instructions on the return procedure. You are responsible for shipping costs on returning items, I cover return
shipping back to you. Please pack the tubes well when returning tubes. Tubes returned which are poorly or
inadequately packed (padded envelopes are not adequate!) cannot be warranteed. Please include a copy of
your email requesting return in the shipment and your return shipping address.
A Very Important Note About Shipping Insurance!!
Shipments may not be fully insured unless you specifically request it! I strongly recommend you purchase full insurance
for your shipments. Without insurance you are responsible for the shipment as soon as it leaves my hands!
The fee is often just what the Post Office charges me. While I will do everything I can to help you locate and track down
a missing or delayed shipment, I cannot assume any liability for missing/delayed/damaged shipments unless they
