Lot deal for NOS Vintage 12AT7-12AT7WA-ECC81-E81CC-6201-6414 Tubes
Asking Price: 55.00

E81CC / ECC81 / 12AT7 / 12AT7WA

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.
