I've got an old stereo receiver with a broken main switch (not
replaceable).
It won't power.

I can solder a jumper across 2 contacts on the switch board (I think).
Then add an in-line switch to the power cord.

Don't know much about soldering ...

What should I use for a jumper? Copper? Other material? Stranded?
Non-stranded?

Anything will work.
Stranded will be easiest because of all the surface area.
