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

What make/model/year? What style switch -- pushbotton, toggle
on toggle off?

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?

Copper. Stranded solders fastest.

How many amps will be passing through the jumper?
