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?


Why the jumper? Just heat one of the existing connections until the solder
melts, pull the wire loose, then solder the loose wire to the other switch
terminal.
