The JJ Electronic 12AT7 / ECC81 is a good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube. It can also be used to replace 12AX7 tubes in position 1 to reduce gain.

ordered set of tubes for resto of a 1956 Zenith am/fm...all NOS -EXCEPT the 12AT7 which was Slovokian 'manuf. This new tube was DEF...produced loud HUM when inserted in radio..suspect cathode leakage...PLUS the tube is HUGE..and barely fits between the 2 ifs..Ive asked for a replacement tube,,,and specified NOS if possible .

I use this tube for more gain in my Leslie speaker cabinet. This goes in the place of 12au7 tube,and this is what I use it for.

My tube chart in my Silverface Princeton Reverb calls for this tube in V2. My tremolo wasn't working when I bought the amp. One site suggested the bias may be off. I went ahead and installed this tube, set my bias (I installed a 10kl pot as per "Uncle Dave on youtube) and my reverb and tremolo sound great. Note: I made no modifications such as holes. The mod I did is fully reversible.
