Vacuum Tube - 12AX7/ECC83, Electro-Harmonix

In stock

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.

It looks like your amp takes one 12AX7 and two 12AU7's. This Electro-harmonix 12AX7 will work and you can find the 12AU7 on our site.
