The Electro-Harmonix 12AX7EH is a preamp tube that provides high gain with ultra low noise. The tube's detailed, musical tone rivals the most desirable NOS types. Unique spiral filament eliminates the filament-to-cathode induced hum common on amps that use AC on the filaments.


Order tubes BEFORE they need to be replaced, and save the gig.

      Comments about Electro-Harmonix 12AX7EH Preamp Tube:

      This is for the picker who is less interested in technical tube talk and more interested in "does it work or not". The EH 12AX7 can, but not always, make your vintage amp sound a little better. If you need the bragging rights that come with purchasing "boutique" tubes, the EH won't do that. The EH 12AX7 will get your amp happy; the money you save will buy LOTS of ramen noodles and other things musicians require! Five stars to Electro Harmonix for marketing a great tube.

      Comments about Electro-Harmonix 12AX7EH Preamp Tube:

      EH markets few tubes, but the ones they do are selected well. As 12AX7's go, there are many to choose from. The EH is a good choice. It has a very smooth and clear voicing. It is neither "chimy" nor harsh and fizzy. The filament, plate, and other components are well designed and placed within the tube showing great care. The end result once in the amp is very noticable and a welcome change from many other tubes that lack the clarity the EH model provides.

      Multi-Tube order

      By Bob Ruszanowski

      from Buffal, NY

      Comments about Electro-Harmonix 12AX7EH Preamp Tube:

      All tubes were correct and functioned very well. Packing of order was one of the worst I'd ever seen for a tube order. Individual tube boxes were thrown in the bottom of the box. Packing tossed in over them. Upon arrival, all tubes were banging into each other in the box. One tubeis microphonic but functions well. Great order processing. Packing needs work.

      Sounds Great!

      Comments about Electro-Harmonix 12AX7EH Preamp Tube:

      I replaced the stock Sovtek 12ax7-WC in my Hartke GT60 head with this 12ax7-EH and noticed an immediate improvement. The EH just seems smoother and more full sounding to me. I think it sounds great and would recommend it to a friend.
