Is there a fusible link in the power transformer?

That's all I can think of.

Any damage done would've (should've) been between the filters installed backwards and the where the power cord plugs into the wall. ;)
That should narrow things down considerably, I would think.
Indeed, usually the caps pop and that's that -- replace the sacrifical caps and life goes on.
I have a CR-1000, but I bought it rehabbed so I don't really know much about the guts.

You probably have the SM already, but, in case you don't, there's a good looking copy at the link below.

EDIT: The schematic is very clean; the P/S is complicated, I am attaching a screen shot showing the 'back side' of the P/S for various territories; looks like a smattering of "real" fuses therein(?).

Good luck!

all the best,
mrh
