Another viewpoint: Just permanently connect the wires (and apply proper
insulation), and switch the amp on and off with a correctly rated switch
in the mains lead.
Or, maybe even better, leave the amp powered-on.

The hole of the original switch can be filled either with the now
non-functional switch, or a nice power-on indicator. Add some creativity
here ;-)

YMMV, Folkert/NL


That's ghetto, much better to fix it right, you might be able to disassemble
the switch and repair the contacts.

Why would it be better to leave the amp on all the time wasting energy? That
stuff isn't free.
