Hi ya all, I'm thinking of building descrete OP amplifier instead of TL081 for two main reasons. Firs of all, that way I'll be quite OK with votages for up to 60 volts (with this version) and secondly, it'll cost me even less than suggested higher voltage replacement OP amp. OP amp is going to be Bryston DOA33 or DOA68 - 8 transistors and few resistors... If it's good for Bryston audio amps I'm quite sure it's going to be quite all right in here. Regards!
