12AY7 Double Triode

Robert814 29.09.2013

I got these to replace 12AX7's and deliberately reduce the gain in my amp. 12AX7's have a Mu (Gain) of 100. 12AY7's have a Mu (Gain) of 43.75. 12AT7's have a Mu (Gain) of 60.5. 12AU7's have a Mu (Gain) of 16.94. It is very simple to unplug any of these and substitute them. I chose the second lowest gain because the amp was really over doing the distortion for the sound I want. There is nothing wrong with the amp, or the tubes. Replacing V1, the first valve, has the most dramatic effect. It all comes down to the sound each of us likes best! It's quite easy to put back the originals if you don't like the sound.

Perfect for lowering the input gain in tube amps

Cesar593 08.04.2018

I have used this tube to replace a 12ax7 in the input stage of a tube amp and, as a result, obtained a more clearer and distortion free sound. Ever been unsatisfied with the grinding sound of your amp, never being able to get a true clean rithm sound? Well, a 12ay7 may be the solution! It worked with my amp.

Sounds good

Dapapa 14.03.2020

Nothing much to say. Sounds good in my V1 of Egnater Tweaker 15 head into a Jensen Blackbird. I play singlecoils. Shimmer is there but then again I also had it with the 12AX7. This AY7 maybe is a bit less agressive, a bit more round, not as hard.

Great preamp tube replacement

Rok84 21.11.2025

I've tried this tube to replace the preamp section of my VHT Classic 6. The tone is warmer and richer than the stock ones (12AX7). Compare to 12AX7 it has lower gain, more headroom and good control of the volume. Easy mounting (pins are equal). Highly recommended. Thanks to Thomann!
