4X NOS 12AY7 and 6X4


#1

Hi - does anyone have these for sale? i am looking for them to build my clone? Another question though, instead of 12AY7, could i use a lower gain tube like 12AU7 ?

thank you

Philip

no, not without redesigning the circuit, then it wont be an M77 clone any longer

If you cant get, or face the cost of, NOS the EH and Groove Tubes Russian made 12AY7 are pretty ok, and generally low noise. Certainly more reliable than the NOS 12AY7/6072A I have here based on my recent experience in a phono amp
