<STRONG><H1><CENTER>12AT7 TUBES CURRENTLY IN STOCK</CENTER></H1></STRONG><BR><HR>
<P><H3>This page lists all of the 12AT7 tubes I currently have in stock, including all industrial and European versions. 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., <A HREF="mailto:[email protected]">please e-mail me.</A>

<P>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.
<P>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.
<P>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.
<P>Here is a scorecard so you can tell who the players are in this family of tubes:
<P><H2><U>12AT7:</U></H2> 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!
<P><H2><U>12AT7WA:</U></H2> 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.
<P><H2><U>6201:</U></H2> 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.
<P><H2><U>6211:</U></H2>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.
<P><H2><U>5965:</U></H2> 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.
<H2><U>6679:</U></H2> 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.
<H2><U>7728:</U></H2> 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.
<H2><U>ECC81:</U></H2> 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.
<H2><U>E81CC or ECC801S:</U></H2> 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. They are both rare, but if you find some they may well be the last 12AT7 tube you will ever need to buy!
<H2><U>A2900:</U></H2>
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!
