I have an old PS Audio 6.0 pre-amp that has developed an odd problem.
When switching in or out of straight wire mode. The unit generates an
ungodly loud POP sound. PS Audio says they won't repair something that
old so it looks like I destined to buy a replacement.

What kind of a switch is it? Rotary? slide? pushbutton? It's probably a
case of dirty contacts.

Incidentally, why do you switch in and out of straight wire mode so often?
I'd be inclined to pick one position and stick with it.
