Did the trick


Verified Buyer

The tweed deluxe amp kit I just finished had a microphonic 12ay7 included in the tube pack. Took a minute to track down to make sure it wasn’t botched wiring on my part. Ordered this new one and it solved all the issues. Amp sounds fantastic!

Verified Buyer

I purchased this tube to try and reduce the input level/sensitivity of my Fender Blues Deluxe. It seems to have some effect to that end, but I haven't had enough time yet to decide whether or not this is a solution. I am happy that so far this tube (unlike 12 AT7, etc.) is not least at lower levels.


I like very much!


Verified Buyer

I put this tube in the V1 socket in my Peavey Classic 30. The best thing I can say about this decision is I was trying to sell the amp because I didn’t care for the tone, now I would never sell it! Made a HUGE difference. And I really like the TAD tubes also. Didn’t care for JJ or the stock Ruby tubes that were there. I put in all TAD tubes, one 12AY7 and two 12AX7, then EL84’s in the power section. Very happy and will buy again.
