This Russian tube is full bodied and bright with a more straightforward presentation. It packs a lot of bite with its higher-than-normal gain. In overdrive, it offers a lot of crunchy fizz. High gain preamplifier tube with ultra low noise and detailed, musical tone. Unique spiral filament eliminates filament to cathode induced hum common on amplifiers that use AC on the filaments. For more information about our 12AX7 tubes, see our tech corner article on 12AX7s.

So much for the spiral filament reducing hum!The tube I ordered hummed like hell. I wish there were more concerned screening going on.

I have not had real good luck with guitar amplifier tubes in my Blues Jr. You can still find some RCAs around if you want to spend a fortune. I still have a good supply of RCA 6L6GCs but no 12AX7,12AT7, etc. I tried some Groove Tubes and some JJ Tesla because a lot of forums built them up. No thank you, never again. I re-tubed the amp with Electro Harmonix along with putting in a a bias adjustment and dropping the voltage so the tubes should last longer and changed out the speaker to a RED WHITE and BLUES Eminence. It is now one sweet amp. I have also had good luck with the higher grade Tung Sol 12AX7s which I put in my Fender Twin.

This "WAS" our standard replacement 12AX7. They are okay, and have more treble than the Tung Sol RI, but they are not the best 12AX7 valve out there, by any means. To me they are a small step up from Sovtek. If you are on a budget and like the sound, fine. I am not very partial to these anymore. For a basic replacement valve we have gone over to the Chinese 12AX7A, and 12AX7B.
