Intermittent scratches/distortion/level changes in preamp

This is where we talk about testing, measuring and repairing things. Sometimes we have to repair the equipment we use to test, measure and repair other things. It's an endless cycle of fixing the broken things we need to fix other broken things.

I wished I had a good cure for silver sulfide on switches.

With stinky "junk" silver coin I use baking soda in warm water in a glass pan with a sheet of aluminum foil.
It pulls the funk right off.
I would never do that with collectable coins but for junk silver dimes, quarters and half dollars it cleans them up.

Not sure how you could make that work for switches...
