250W Simple Power Amp Project ??

Hi everyone,

I need to upgrade an aging Yamaha P2250 Power amp with something I can build myself. It is being used as a PA amp for a small church. I own an Adcom GFA-535 and absolutely love the sound, and am looking to build something like the equivalent of the beefier GFA-555.

Any suggestions??

I have the service manual with schmatics for the GFA-555 (mk i), and I am wondering about recreating a clone of it, as the circuitry is fairly straightforward. Etching pcbs is no problem for me.

Anyone have any comments?
