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.

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.
(2) 6CA7 Sylvania branded Peavey, test new but they are not close to a matched pair, one has a bit of typical Sylvania getter rainbowing; $34.50 ea.

(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!
7591A Tung-Sol - just a few in stock! Please email me for details and/or to purchase these tubes!
Important note - updated! 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 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) or .22 uf. 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 need to use. 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.
7695 Sylvania branded GE, NOS/NIB, these are 50 volt beam power tubes, $12.50.
7868 Electro Harmonix, same size bottles as NOS, great to have new production tubes! $29.50 ea., $59.50/pair,
$119.50/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.
(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! Not quite as warm as the SED, but mellower than the EH; $22.00 ea., $44.50/pair, $89.50/quad.

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 $45.50, pairs are $91.50, quads are $184.50.
Genalex Gold Lion KT-88 reissues - good stock on hand! The listening reports are virtually unanimous, regardless of what gear the tubes go in.
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.

6CG7 Electro-Harmonix; the NOS supply is getting really thin - especially if you wanted multiple identical tubes or a matched pair - so
I decided it was time to bring another excellent quality EH tube into stock. These tubes have nice section match, low noise, and sonics that
make them a fine choice. I think they are a very fine tube. Just $18.50 ea. or $39.50 for a matched pair. My price includes testing you pay
$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
the gold plated pins makes a real difference in the quality of the pin-to-socket contact. If you do a lot of tube rolling, if you have a
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
matched pair. Again, my price includes testing you pay $4.00 or $5.00 extra for from some other vendors!

6922 Electro-Harmonix... this tube offers very low noise and microphonics, with the best durability
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 $13.50 ea. single,
$28.50 for gain matched pairs, and $33.50 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.

That's much less than you'll pay for even Russian 6SC7 tubes at many vendors! I also have about
3 used that are new or near new testing used for $9.50 ea. Note: My small tube damper rings fit these

(1) 12AT7 RCA, NOS in old distributor box, black plate, square getter 1962 tube. This tube

(3) 12AT7/ECC81, one branded "Amperex", one branded Sylvania 12AY7 (!) but are really E. German RFT

(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

(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!
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 $12.50 ea. or $25.50/pair.
Genalex Gold Lion B759/ECC83/12AX7 reissues! Tis is a great tube - warm, excellent (one customer described it

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.
(1) 12AX7A Realistic gold pin, made in Japan, used but tests close to new, nice tube! $19.50.
*Sovtek 12AX7LPS tubes, very low noise spiral filaments, checked for good section-to-section match, $14.75 ea.,
or $29.75 per matched pair; quads (if available - these are VERY rarely needed) are $61.50. For specially selected tubes
(for Aesthetix and other hi gain/noise sensitive gear) selected pairs (when available) are $37.50. 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., 4 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.
(1) JG-5751 GE, ANOS 2 mica grey plate tube with matched/balanced sections in a white box, $14.50.
Now In Stock! 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!!
Closeout! While they last - 5751 Sovtek, it uses the same long plate as the very nice 12AX7LPS, Sovtek 5751s are
nice tubes so grab these while you can; $13.50 each, $27.50 for matched pairs (if available). Save $4.00 on singles and
$9.00 on pairs!
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
(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.
(2) 12AY7 RCA, NOS/NIB grey plates, one with very low noise/microphonics and balanced sections for $44.50; the second 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 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 $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!

(12) 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!

Tube shipping is usually $7.95 to any USA address (up to 2 pounds. 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). 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 $7.95 discount on the return shipping. If this is not
clear please email me withyour 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
