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.
