I often come across corroded or dirty contacts so the amp stops functioning.
If the spriginess of the metal has failed then replace obviously, but what
about the more usual case where it is only corrosion/airborn contaminaion,
not really necessitating pulling the amp apart to replace them. Any ideas
how to deal with.
1/ solvent clean the contact/s
2/ abraid the contacts with file
3/ coat the contacts with something
3/ add compressible material , glued in place, over the spring section to
add closure force
4/ if the sockets are never used for effects etc , bridge tightly across the
contact with fine copper wire, soldered in place, "shorting" the switch - if
plugged into at some future point then the wire will break
5/ any other ideas to reduce the possibility of re-occurance


Clean the ones that respond and replace the ones that don't. The worst part
about this is that you will have to test clean to know if it works. This is not
nearly so big a deal as you make of it.

Burnishing works. I can't see why you object to the concept.

The Cliff type jacks are not usually problems and really don't require this
overcomplication you're bringing to the subject. Annual execise by the user and
the occasional professional cleaning keep them in shape. You can complain about
the aesthetics, but they work fine and have for decades.
