Hello ,
I'd like to build a 400W powered amplifier for small signal input from a microphone source to amplify vocals out of PA speakers. I have found the following schematic and I have two questions for whomever is willing to help:
1) Is this circuit adequate for the application?
2) What type of power source should I be looking for (current output) for the +70V and -70V connections?

Thank you so much for your help.
