OP AMPS, crossovers

sauuuuuce · 18th September 2004, 02:26 AM

Getting ready to build an amp. First stage is going to be a tube pre........second stage is going to be an active two way crossover......then mosfet Class AB output stages. Any suggest op amps to use in the crossover circuit? The only things I have on hand now are 741's........looking to buy something more suitable to audio usage.

You can start with OPA134. It's a good start.
