Going by the rusty cabinet screws on a lot of the kit I see they must be
stored in sheds or garages.
Anyway this example I "abraided" with a cut segment of nylon cable tie and
"Brasso" metal polish, cleaned off by a strip of card dampened with meths.
Drilled a hole through the board either side of the switch and tied some
silicone rubber cordage around the switch passing through a piece of plastic
barrel that seated neatly in the top of the flexing metal strip.

Hold on... did you just say that you DRILLED HOLES through the circuit
board of someones possibly valuable/precious amplifier! after 'abrading'
the contacts with a chunk of CABLE TIE! and BRASSO!

Electrolube make contact cleaning strips specially for the very job of
cleaning contacts (the clue is in the name) they are pink and they work
- for a while, then the problem comes back.

Look.. don`t **** about, just replace the damn sockets with new ones
add a drop of Elecrolube from one of those squeezy pen things right on
the spots where the contact is made and Bob's your uncle as we say over
here.
