(5) 8448 Tung-Sol branded Motorola, may be new tubes (?), B9A based like a 12BY7A, 12DQ7, or 12BV7. It looks like

(2) GL-8005 GE, NOS in white boxes. These are rare and scarce, so if you need 8005s , grab these now!
Important! One of these tubes has a piece of metallic looking material loose inside it. It appears to have been left in
the tube when it was made, as nothing is broken inside that I can find. Normally a piece of metal in a tube is trouble,
but because of the size of this piece and the fact that the glass "press" covers the base leads the metal piece is only
a problem if it somehow lodges inside the plate structure which is extremely unlikely. So you can use the tube with
complete confidence as long as you use it upright, in a vertical position. Both tubes test great, and if you aren't
satisfied I'll refund your purchase! Any reasonable offer accepted! They were $49.50 ea., or both for $95.00.

(2) 6939 Amperex USA, rare frame grid tetrode tubes, new, white boxed, $29.50 $22.50 ea.

Recent Arrivals!

All tubes (even new) are carefully tested on my AVO CT-160, TV-7 or B&K 747 testers. Power tubes are tested
and matched at real operating voltages, not just with a tube tester. BTW, NOS means new old stock, ANOS
means almost new old stock, and NIB means a new tube in the original box.

What's Up With The 6900s? These tubes were returned to the vendor, as he sent the wrong items! The replacement
tubes should be here at some point, they are long overdue. The prices listed below will not be changed regardless of when they arrive:

NOS testing pairs - $475.00/pair; Good/near new testing pairs - $425.00/pair. Singles - new testing for $229.50, near new
for $205.50. There will likely only be a few pairs. Insured shipping is required for the 6900 tubes.

One single - it tests good, but just barely passes the grid current test. It probably just needs to be run in to improve,
but even without any improvement it is a good tube. $119.50. Note! This tube is in stock!

***********************************************************************************************************

Genalex Gold Lion B759/ECC83/12AX7 reissues! Reports are this is a great tube - warm, excellent (one customer
described it as "sublime!") midrange and super soundstaging. The latest tubes are much quieter, I can now recommend it for
phono and or other noise sensitive stages. $43.50 ea., $88.50/pair. Now in stock!

Genalex Gold Lion B749/ECC82/12AU7 reissues - now available! This tubes has warmth, and the noise level
is far better than the initial batch. The track record is clear - these Genalex reissue tubes are superb! $43.50 ea., $88.50/pair.

Genalex Gold Lion E88CC/6922 - now available! 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 true premium 6922, every bit as good as the best NOS - at a fraction of NOS prices!
$44.50 ea., $89.50/pair.

For the "finicky" gear out there you can request my Genalex"Select Grade" 6922. These tubes are tested for:

Transconductance
Gain
Plate current/DC balance(twice!)
AC balance/section balance (twice!)
Noise/microphonics (twice!)
Shorts
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. $57.50 ea. or $119.50/matched pair when available.

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.

Genalex Gold Lion KT-66 reissues - now available! They look good, they are rock solid on the the burn-in/match rig,
reviews are superb - and after the incredible performance of the KT-88 Genalex,I didn't want to wait to get these in stock!
$39.50 for singles, $79.50/pair, or $159.50 for a quad. Please note - these tubes have a special shipping rate to any USA
address of $6.00 for a quad (outside the USA is higher & some exceptions apply).

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!
Price Cut! Singles are $44.50, pairs are $89.50, quads are $179.50. Please note - these tubes have a special shipping
rate to any USA address of $6.00 for a quad (outside the USA is higher & some exceptions apply).
Special! (1) pair with tilted glass bottles, electrically perfect - fully guaranteed! $79.50/pair.

Genalex Gold Lion KT-88 reissues - good stock on hand! The listening reports are virtually unanimous, regardless
of what gear the tubes go in. This tube is clearly the equal of and according to many may 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. Pin soldering is
excellent! There have been just a small handful of the over 3,000 tubes I've sold that have had any issues at all.

Singles are $54.50, matched pairs are $109.50, matched quads are $219.50; octets (when available) are $440.00.
Note - these tubes have a special shipping rate to any USA address of $6.00 for a quad (outside the USA is higher
& some exceptions apply).

Extended Purchaser Protection Coverage On The Genalex KT-66, 77, and 88!

I have said over and over that the quality of the KT series Genalex is excellent, so I'm "putting my money where my
mouth is!" Effective with tubes purchased on or after October 1, 2010 and until further notice the following applies:

1. The tube is covered by the maker's own 90 day warranty. The warranty terms located at the bottom of this page apply.
2. Tubes out of the maker's warranty but less than 210 days (7 months) old will be replaced at 30% off the current selling price.
For example, as of November 2010 the KT-88 price is $54.50 ea., so 30% off is just $38.15 ea. The warranty terms below still apply.
3. I reserve the right to alter, modify, or discontinue this enhancement at any time. However this will not impact coverage
already in place.

The extended coverage applies to the original purchaser only, and applies only to tubes purchased from me, not tubes provided
under the coverages listed above.

says about them: "Due to its rugged construction and conservative ratings, it is the most reliable current production EL84 type
available for use in Vox AC-30 type amplifiers. In addition, its linearity and tone characteristic make it the ideal replacement
for EL84 hi-fi amplifiers, such as those built by Fisher, Scott, and Harmon-Kardon."

Genuine 7591A Electro-Harmonix tubes are 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."

Important note! There have been some cases where the new production 7591A tubes have had trouble in circuits
using a very high value grid resistor - as vintage Scotts, Fishers, and others do. The best solution is to change all the grid
resistors to 180K-200K (from the old value over 300K - sometimes they even exceed the old RCA tube manual
recommendation!), and change the coupling caps to .1 uf or .22 uf. I stock all the parts you need, the parts cost is only
$15.00 to $20.00 per amp, depending on the coupling cap value and voltage. Please note 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.

7868 Electro Harmonix, same size bottles as NOS, great to have new production tubes! $26.50 ea., $54.50/pair,
$109.50/quad. Properly matched by me personally at 425 volts, not just "distributor" matched! Note - the pins on the
EH tubes are larger than old stock, and require very careful installation. After the first time they are installed
it's much easier to do.

(2) 7868 RCA, NOS/NIB, the real deal! Very hard to find these days, $54.50 ea.

(1) 8552 RCA, NOS but came in a Motorola box, it's a 12 volt 6146 (same tube as 6883B), $17.50.

is used/white boxed and tests near new - but the getter is worn to the size of a US nickel, $21.50.

(1) EL34 Mullard xf2 branded RCA, single getter, black base, used but tests brand new, $99.50. Note: I had another
one of these I got at the same time, but (SOB!) it shorted on the high voltage test rig! Very sad...

Mullard reissue EL34 tubes. These were modeled after the xf4, and the people who've heard
the tube like it a lot! Not quite as warm as the SED, but mellower than the EH; $22.00 ea., $44.50/pair, $89.50/quad.

SED (formerly Svetlana) EL34, made in St. Petersburg! $26.50 ea., Note: Only three singles

too. Only $32.00 ea., $64.50/pair, $129.50/quad. Note! If you want to use these in a Harman-Kardon Citation II
amp you must reduce the bias current to 83-85 ma. or so to stay within the tubes' dissipation limits.

Now In Stock! KT-90 Electro-Harmonix (EH). I now find that these recent production EH are much better
both on the test bench and in listening reports. I now keep a good stock on hand - matched right by me personally!
Pairs are $89.50, quads are $179.50.

In Stock! KT-120 Tung-Sol. Rugged power tubes with significantly higher dissipation limits than the KT-88 or KT-90
I am now keeping 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 $46.50 ea, pairs are $94.50, quads are $189.50.

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!

Electro-Harmonix 12AX7EH short plate tubes, great in guitar amps, used by many audio makers as original equipment!
100% noise and microphonics tested, take them for only $11.50 ea. or $24.50/pair.

Mullard reissue 12AX7 long plates! Another new production tube getting excellent reviews! One more fine quality

Important!! The new batches I'm receiving are EXCELLENT quality, I have good stock on hand, ready to ship!

Just In! 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 plate (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, $13.75 ea.,
or $29.50 per matched pair; quads (if available - these are VERY rarely needed) are $59.50. For specially selected tubes
(for Aesthetix and other hi gain/noise sensitive gear) selected pairs (when available) are $35.50. 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. $15.50 ea., 3 or more singles just $14.75 ea. Matched pairs are $33.50/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. $29.50 ea.,
matched pairs are $59.50/pair.

In Stock! 5751 Sovtek, using the same long plate as the very nice 12AX7LPS, Sovtek 5751s have received many
very positive reviews. The NOS is about gone, so here's a proper 5751 at a great price, $17.50 ea. or $36.50/pr.
Remember, my price includes testing others don't do or you pay extra for!!

************

Rare Tubes! (12) 12AY7 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. Here's what I have:
(1) matched/balanced very low noise pair - $79.50
(1) matched/balanced low noise pair - $69.50
(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.

Great Tube! 12AY7/6072 EH Gold; just like with the 5751 the NOS supply is about gone, and what's left is
getting very pricey. The gold-pinned EH is an excellent performer, and while I rarely opt for the gold pin EH tubes, these
may end up in critical locations where the gold will be a real benefit. These have vertical rib plates, just like old GEs - the
plate is unlike any other EH tube I've seen! It won't break the bank either, at just $37.50 ea. or $76.50/pr.
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!

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 $16.50 ea. or $37.50
for a matched pair. And again, my price includes testing you pay 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).

(14) 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!

For USA orders just drop me a check (personal is fine) or money order - whatever is easy for you - for the
total amount due and I ship promptly via USPS Priority Mail upon receipt.

International shipments are no problem! Contact me regarding details and shipping charges. Purchasers outside
the USA must make payment in US dollars. Checks must be payable by US banks. I'm sorry, but I cannot
undervalue shipments to reduce your counrty's duties. I can be fined/jailed for doing so, so please don't ask.

Note! Regardless of how you pay, it's best to e-mail and confirm availability first: jimmcshane@prodigy.net

Tube shipping is usually $7.00 to any USA or address, and it's only $6.00 with a purchase over $200.00 (up to 2 pounds, USA only).
Shipments to Canada up to 1-2 pounds are about $16.50 - $32.50 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).

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 are not insured unless you specifically request it! I strongly recommend you purchase 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
are insured.
