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.

Tube measurements are as follows:

  • Height: 2.75” (without pins)*
  • Diameter: 0.87”*

*Note: Due to the method of production in regards to the glass, measurements may vary slightly.

See my review on Electro-Harmonix 12AX7. I bought the matched pair of EL84s and I now have a completely different amp (along with a few other changes)

Awesome. Quick delivery, solid packaging and the tubes I bought work excellent! Thank you

Great sound, very clear with good headroom and a nice tight crunch when cranked although I use a Digitech unit for driving it. Installed it in my Blackheart BH5-112 which I use to gig with every weekend after I mic it up. Small amps are the way to go. I started with a Fender Deluxe Reverb and went up in power from there and now down to using a 5 watter! Great price on tubes, great service and now my main source for amp parts.

I don't know a ton about tubes, but I put these in an old Univox amp to replace a pair of failing Sovteks. I prefer to use a volume boost pedal and let the power tubes distort for a more natural, dynamic sound vs using dirt/fuzz pedals. To my ears these were louder (could just be that the old Sovteks were toast) but certainly a more well balanced distorted tone, full lows, mids and highs. Sounds pretty great right now, I'm happy with the purchase.
