A buddy has an older SimAudio Celeste power amp. He accidentally shorted the speaker terminals on one channel. He replaced the fuse but now it won’t stay on and the AC power relay opens within seconds of power up. Any idea what in general could cause such behaviour? Can’t tell if the channel with the blown fuse works as he says it shuts down too quickly to tell. Thanks.
I have the smaller 4070 so I’ll look at the schematic if I can get it from the fellow here on DIYAudio that has it. Likely the same but with more output devices on his. But yes it sounds like it’s damaged.
