We have here a Crown PSA-2 stereo amp for monitoring purposes which I am
currently renovating. It employs TL074 and a single TL071 on the main board
driving the output power transistors. Would it be possible to replace with OPA4134PA
or OPA4132PA without upsetting some other super-tuned parameter in this circuit?
Schematic can be found here: http://www.crownaudio.com/pdf/legacy/psa2schematics.pdf
The single opamp on the left is TL071 while the ones in the middle are TL074 quad package.
Also, what do people think of this amp?
Thank you.
