Anyone got the schematics for a Crown XLS5000 ? I'm most interested in the
board that the mains comes in to. There's a bloody great disc something
inside a big lump of heatshrink, and serious flames shoot out of it before
every trip and fuse in the workshop goes out ...

If I bring it up on the variac, I can't get beyond about 20 volts before the
poor thing is jumping off the bench, so there's a good short on there
somewhere. I initially thought that the disc might be a big VDR that was
short, but looking up the part number on the second one that's on there for
the other half of the amp, it appears to be an inrush thermistor, so I guess
whatever is short, must be south of that ...

Hey guess what? Today I received a Crown XLS 602. (a baby by comparison)
And guess what? The mains Transformer is open circuit.

This TX is marked "NRE Electronics Manufacturing Co Ltd.

Dunno if that makes it from the same source or not.
