Hello,
I would like find an OP AMP to use in this amp but with more voltage rails
Do you know an High voltage and High gain OP AMP ?
Thanks a lot !!
You can just supply the opamp from +/-12 or 15V and the rest of the amp of a higher voltage. Just make sure the transistor max voltage is not exceeded.

I have OPA627 and 637 witch support 18V rail

Do the stages after the OPamp have enough gain? Or does the OPamp output need to reach close to rail voltages?
