Modified ESP 3A amp.

[Freddie]

I need a cheap/simple amp for biamping purposes. Since I already have two 500VA 2*38V toriod transformers I wan't to use them. But this will create +/-50V a little bit too high voltage for the ESP3A amp, I will use 4 ohm speakers.

So I did some changes to the circuit, but I'm not 100% sure that it will work OK. I know the outputstage could be smaller, but I like when things are a bit oversized.

Suggestions?, Comments?

Turn up your spice simulator and check the bodeplot for phase margin with ~ 8Ohm||100nF load.

Hopefully your modified amp do not turn more than 160degress. Maybe check the old design too. If they are identical ... Nearly identical i would build
