Hey all, I have searched around and can't seem to find a suggestion for how to power up amps that have been sitting for who knows how long. I inherited a number of PL amps from my dad and don't want to just toss power to them and pray. Can someone suggest a smart way to wake these up to find out what sort of condition they are in. I did slowly power a 700 up with a variac and it didn't do anything odd. Then plugged in my phone and it played some sound. But when I went to a little more volume it popped the main fuse. Fuse was black inside. So I have stopped there. Don't want to cause problems unnecessarily.
Thanks
