My guitarist has an old Peavey M-3000 monitor amp. It says it will put out 3000 watts into 2 ohms. It has a huge fan and big ol' cooling fins on the back. It is a "mono" amp, but I think it would be great for a pre/power setup. Currently, he has it hooked up to his church youth meeting place's PA. It actually sounds pretty clean. I was wondering if anyone has used one of these?
