The EH 12AY7 from EHX, also known as the 6072A, appears in many vintage amps. A great valve for improved headroom.
Pin compatible with the ECC83 (12AX7), but with lower gain. Used in a good deal of early Fender Tweed amps as the first preamp stage (V1 valve position). Many harmonica players favour this valve in the V1 position.
We test every valve ourselves on our in-house valve testers.
Includes a 180 day from receipt warranty (excluding user-caused mechanical damage) for peace of mind.
