12AT7 TUBES CURRENTLY IN STOCK


This page lists all of the 12AT7 tubes I currently have in stock, including all industrial and European versions.

It is a long page, use your scroll button and scroll down the page to see it all.

These are extremely high demand vintage tubes, so I have these listed on their own page, as my stock changes rapidly. If you need a quantity of these tubes, or have specific needs such as matching, special construction, etc., please e-mail me. NOTE: Our inventory is being simplified to show that we either have adequate stock on hand ("in stock"), are out of stock ("temporarily out of stock"), or stocks change very rapidly with rare, high demand tubes ("call/e-mail"). Stock levels with actual quantity on hand shown are being phased out as we update inventory. The only exception to this will be very scarce tubes where we typically will only have a small stock on hand. Of course, any time you need a large quantity of tubes of any type, is is a good idea to email us for a stock check first.

NEW! CURVE TRACER MATCHING AVAILABLE! We can match most small signal preamp tubes on a Tektronix 576 curve tracer. Scroll down to watch a brief video about matching below. This runs the tube at full rated plate voltage, and plots the curves at 10 different grid bias levels. The most accurate method to test tubes, the curve plots can actually be compared to the printed examples for each tube type that appear in the manufacturer technical data sheets and books. Each triode of a 12AT7 can be compared both internally (balanced) and to other tubes (matched). Curve tracer internal balancing, or matching of two or more tubes on the curve tracer, adds $10.00 per tube to the cost and is done upon request. Prices listed below for "matched pair" tubes are Gm matching only, and there is no additional charge for Gm matched pairs. For most uses, Gm matching is fine. Curve tracer matching would be recommended if the tubes are to be used in a phase inverter circuit, phono or microphone preamp, or other critical or demanding circuit. Curve tracer matching is an additional special request item and is charged in addition to the listed price of the single or matched pair tubes on this page.

The 12AT7 is a high-frequency twin triode in a small 9-pin miniature glass package. This tube has a mu factor of 60, as compared to the higher gain 12AX7 with a factor of 100, and the 12AU7, with a mu of only 20. As you can see, it shares similar pin connections with it's cousins, but these tubes are not interchangeable. The 12AT7 is found in many high fidelity applications, as each triode section in normal use operates as a class A amplifier. They also turn up in line and microphone preamplifiers, musical instrument amps, and vacuum tube equipped recording equipment. By their design, they are inherently low noise, making them a good choice for these applications.

What's hot these days with these tubes? Right now, most of the vintage 12AT7 tubes are a great bargain, as the spotlight is still on the vintage 12AX7 and 12AU7 varieties. Both the USA and West Europe versions of this tube are just as well made as their famous cousins, but they were used less in hifi gear, and more in professional preamps and recording equipment. Those of you with a hifi preamp using the 12AT7, as well as owners of pro line and mike preamps, will find a refreshing change from the usual high prices of other vintage twin triodes. Both the vintage USA and European versions of this tube are excellent. I can't think of any brand, even "off brands" that made a crummy vintage 12AT7. Of course, the stellar performers are still the big boys: Telefunken, Mullard, Amperex, and RCA.

Nearly all of these tubes contain a pair of tiny "wing shaped" plates. These resemble airplane wings with a rounded front edge and a tapered opposite side where the plate is joined by a rivet or weld, and the two plates point in opposite directions. The only difference is in the RCA 12AT7WA military versions, where the plates look like tiny 12AX7 rectangular plates.

Here is a scorecard so you can tell who the players are in this family of tubes:

12AT7:

The "garden variety" of USA made versions of this tube. All I have seen have the wing shaped plates. The early versions have blackplates, the later (1960s, 1970s) have greyplates. All seem to be top getters, with either a square or D shaped top getter. All are great tubes, and the finest (like the RCA blackplates) are on par with the military and industrial versions. Sometimes "selected" versions of this tube turn up. Often made by large manufacturers like RCA, they are usually labelled with the brand of the product they were selected for. Most often electronic organ brands are found on the label like Baldwin, Wurlitzer, and others. Sometimes hi-fi and musicial instrument amps had select tubes made for them, and labels like McIntosh and Fender turn up. The tips of these tubes are usually painted a color, indicating they have been screened for low noise. These tubes are a great buy when they turn up!

12AT7WA:

This is a military version of this tube, and may also be listed as a 6201. Some tubes have both type numbers on the label. These usually have thick mica spacers. The RCA versions have extra support posts and tiny "12AX7" type plates, nearly always black. This tube is usually very low in microphonics due to it's rugged construction.

6201:

Frequently, this number appeared along with 12AT7WA (military version) on the same tube. However, some brands made the 6201 as an "industrial" 12AT7. Sylvania made a 6201 in their Gold Brand line, and it came in the distinctive gold box, had gold lettering on the glass, and most (but not all!) had gold plated pins. Amperex made a very nice PQ version of the 6201 with gold pins. A few 6201 tubes, usually early ones, have an extra mica spacer on top, known as "triple mica", and are noted for lower microphonics. Overall, this tube is a step up from the standard 12AT7, and most were made to meet military specs so that both military and industrial versions could be manufactured on the same assembly line.

6211:

This unusual tube is listed as a frequency halfer, in addition to being a class A amplifier dual triode with medium mu. Medium mu means it has lower gain than the typical 12AT7, in fact lower than even the 5965 listed below. It also has much larger, flat plates that have diamond shaped points at the corners bent inwards (in the versions I have seen) that seem to add rigidity to the plate structure. This tube also has slightly lower plate voltage and current ratings, but not enough to make a difference in hi-fi use. I have seen it used in preamp circuits, and it's lower gain and lower microphonics (thanks to the large plates) probably contribute to a mellow sound. I have an amp where this tube is used interchangeably with a 12AT7, and there is a difference in sound between the two types. These are hard to find, but you may want to try them to see how a medium-mu tube sounds in place of the standard 12AT7. Just the thing to tame down a screaming guitar amp or shrill stereo system.

5965:

This industrial tube is close enough to the 12AT7 that audiophiles have started buying them up and commenting on the low noise of this tube. It most likely is because it has a lower gain, a mu of 47 compared to 60 of a 12AT7. It is kind of like using a 5751 in place of a 12AX7--the lower gain being the main difference. These tubes are still plentiful, and are really well made. GE made a fine version of this tube in their "5-Star" broadcast line. A few have an extra mica spacer on top, known as "triple mica" and noted for lower microphonics. There is also a rare Telefunken version of this tube with long plates.

E180CC or 7062:

Most often found in European types, typically Amperex or Philips, this tube is virtually the same as a 5965 in regard to electrical specifications. Audiophiles have been seeking it out since the price is generally lower than the premium ECC81 NOS prices currently. Like the 5965, it has slightly lower gain than the 12AT7, and has the added advantage of a 10,000 hour heater life to make it another audiophile "secret" tube. A super bargain when you find them, since they are musical and smooth to listen to, and actually sound better than many standard 12AT7 tubes. Better grab them now while the prices are still low! Be on the lookout for the rare Holland D-getter types from the late 1950s, and the even rarer "pinch waist" types with the narrow glass middle section. These are superb tubes. This tube is about a half-inch taller than the standard 12AT7, so chassis space is an important consideration.

6414:

An industrial, computer rated dual triode,virtually the same specs as the E180CC or 7062 listed above. Unlike the E180CC, this tube was made in the USA. It is a more rugged build, with the Raytheon blackplate type sporting triple mica and military ratings. This tube is also like a 12AV7 and will work wonders in any 12AT7 spot, and may be just the ticket if you want to boost the gain of a 12AU7 circuit. The 6414 is getting very hard to find, but with a 10,000 hour heater rating you may never need a replacement. Discussion groups rate this type very highly for use in headphone amps. Stands about 1/2 inch taller than the standard 12AT7.

6829:

Yet another industrial tube that is very similar to the 5965. This one has a mu factor of 47 so it is slightly lower than the typical 12AT7. Those I have heard are rich, detailed, warm, and thanks to the lower mu, very quiet and low in microphonics. GE made these in their 5-star and military line so they are a rugged and long lasting tube. Like the E180CC, this tube is about a half-inch taller than the 12AT7, so you need to consider overhead chassis or cabinet space when swapping a 12AT7 with one of these. An excellent audio bargain now, but prices may soon climb as audiophiles discover them!

6679:

This is an industrial 12AT7 designed for mobile communications use. It maintains it's output even if the filament voltage varies. Nice tubes, but they never have been too plentiful. They will work fine in hi-fi use, and are a step up in quality from the standard 12AT7.

7728:

This was a high-end industrial tube made by CBS or Hytron (same factory made both, actually) with gold pins. These are nice tubes, but are very scarce. I rarely have them in stock.

ECC81:

This is the European version of the 12AT7, and is identical to it. The Telefunken even has the wing shaped blackplates, just like the RCA. Great tubes, equalled only by the RCA blackplate or the military/industrial versions. Even those made for USA hi-fi products in the 1960s (Knight, Bogen, Daystrom, Dynascan, etc.) are excellent tubes, and have the fine sound quality of those with Mullard, Amperex or Telefunken labels. These tubes currently are a bargain, and they blow away the Russian and Chinese trash being made today. The rarest are the 1950s versions of Mullard and Amperex with a "D" shaped top getter said to sound on par with the scarce A2900 listed below.

E81CC or ECC801S:

This is a rare tube, usually found only in the Telefunken or Siemens brand. These tubes have been screened for audio use and low noise, and have a 10,000 hr. rated life on the heater. The ECC801S are by far the rarest, and the E81CC only a little more common. Both are excellent, low noise, finely crafted tubes, with the E81CC being the best value currently when compared to the recent spiraling rise in the ECC801S prices. They are both rare, but if you find some they may well be the last 12AT7 tube you will ever need to buy!

TS65:

This stands for "Telefonica Serie", and these rare gold pinned gems were made for various European telephone networks. As most European countries had government controlled telephone and communications networks, these tubes were made for the government and are essentially military spec. This would include features such as 10,000 hour heater life, gold pins, matched internal triode elements, low noise, uniform output under harsh operating conditions, in short, the whole enchilada. Most were labeled for Philips, rare ones were made by Valvo. Watch for the uber rare 1950s D getter and pinch waist versions. I would stack them up against the very best NOS ECC801S and A2900 tubes in quality!

CV4024 and M8162:

Fine British military tubes from the 1960s and early 1970s. I have seen mostly Mullard examples of these, although Brimar did make some. Depending on the manufacturer, the tube may have both numbers on it. The rarest and best are the early Mullards labeled with M8162 and the shield logo. These are all military tough, and have that sweet rich British tube sound. Most of the Mullard military tubes were made at the Mitcham, UK factory, which made most of the British military tubes.

CV455:

Another British military type of 12AT7. Usually Brimar was the maker of this fine tube, with the earlier versions from the 1950s being the most desirable. Watch for the versions made in the 1970s. These have wing shape black plates and a sound close to the earlier type, at often half the price!

6060:

This rare tube is the Brimar answer to the Genalex A2900. It has a similar construction to it. These are sometimes called the "Yellow-T" tube due to the large capital letter "T" in a yellow triangle on the glass. The best of these were made by Brimar at their Footscray, UK factory in the 1950s. Virtually all of these are phono grade, they are very quiet. There are later versions with the "T" logo on a white triangle, but these are not as desirable, sonically, and when found should not be nearly as expensive. The Yellow-T tubes are remarkable for their air, realism, and seductive warmth, and unfortunately are getting as rare as the A2900 tubes!

A2900:

The even scarcer A2900 is in the "Gold Monarch" series by Genalex. Genalex was the premium line of tubes produced by the Marconi-Osram Company in England. It has wide, flat black plates and white lettering on the glass, the words "Gold Monarch" in white script, with the red Genalex decal logo around the top of the tube. There is also a British domestic version with the grey and blue GEC decal on the glass, that was not exported. These are true audiophile tubes, with tightly controlled noise specs, designed with audio perfection in mind. Any scarcer and these would be museum pieces!

OK, SO TELL ME HOW THEY SOUND!!

A tough question if there ever was one! The best advice is to get a few types and hear for yourself the good sounds you have been missing. All of these vintage tubes are excellent, much better than the Russian or Chinese yuck that is being made today. When replacing any stock Russian, Chinese, or East Europe tube with any of these vintage NOS types, you will notice immediately that the midrange glare is gone. Gone too is that honky, boxy quality, and the tiring upper midrange screech that current production tubes are famous for. Here are some VERY GENERAL observations about some of these vintage tubes:

TELEFUNKEN, SIEMENS, VALVO, LORENZ, and other German made NOS: These tubes are usually characterized by an impressive open "air" at the top end. The soundstage is large, even in mono applications these tubes have a great 3-D image. The midrange is ruler flat, and the bass is tight and accurate. These tubes have a fine sense of dynamics, and most are impressively quiet. These are not "warm" tubes, and to some ears their lack of midrange warmth may be heard as bright. I tend to think of them as accurate, and their clean, focused sonic image is astonishing. My personal favorites. For critical phono or microphone preamp needs, grab the rare Telefunken or Siemens ECC801S before they are gone! They are absolutely incredible tubes that will never be made again!

AMPEREX, PHILIPS, MAZDA and other Holland/France/Belgium made NOS: These tubes are a great balance of a clean, airy top end, nice midrange warmth, and accurate bass. They are very pleasant, clean, and musical to listen to in hi-fi applications. Unlike other clean European tubes, these break-up impressively when overdriven in a guitar amp. The rare longplate versions are the same, but with even more soundstage space and detail. The Mazda adds a nice bit of dynamic punch to the sound.

MULLARD, GENALEX, BRIMAR, and other British made NOS: Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions. The top end is silky and pleasant, without being rolled-off. The best of these tubes retain a fine sense of "air" at the top, and the upper midrange is smooth and liquid. These tubes reproduce the human voice, especially female voices, with haunting realism. The rare D-Getters and Genalex versions have an eye-popping huge soundstage, razor sharp focus and detail, and an uncolored top end while retaining the warmth of the lower priced versions.

RCA, RAYTHEON, GE, SYLVANIA, and other USA made NOS: This group is very diverse. The RCA, Raytheon, and Sylvania blackplates are among the best here. These are very musical tubes with air and sparkle at the top end, warmth in the mids, and great bass. The RCA are drop dead beautiful in guitar amps, even the lower priced greyplate and longplate versions. They also have a wonderful "phat" gritty sound when overdriven in these amps. The blackplates and most tubes made for organs are very quiet. The greyplate GE is an all-around nice-guy tube to listen to, the blackplate here possibly getting the nod for hi-fi use. The Sylvania greyplate and military versions are clean and a bit bright, but the Sylvania 6201 variants are very balanced and pleasant to listen to for hours. The RCA 6201 and 5965 is more like the Mullard, with a rich warmth and wide bandwidth. Currently, the USA made tubes are a nice surprise with their low prices as compared to the European types.

SPECIAL! 12AT7/5965 GE special side-getter cleartop 5-star Industrial GradeMATCHED PAIRS

New Old Stock Original Box and white box. Rare early 1960s GE 5-star tubes with dual side getters and cleartops, large 12AX7 type plates. These were made for industrial use, and can take long periods in full cutoff without changes in characteristics. With their higher plate voltage ratings and slightly lower gain than a 12AT7, they work wonders in any amp, preamp, or guitar amp! I have listened to a pair of these, and they are rich, with a lush, warm midrange similar to Mullard. Totally quiet with no microphonics thanks to the lower gain, and rigidity of the dual side getters. Plug and play 12AT7 replacements. A few labeled for IBM and International, with "12AT7" printed on top of the 5965 label. Hand selected, carefully matched pairs. They go fast at this price! SINGLE TUBES JUST $16.00 EACH.
