I'm pulling out my older RF gear 1 by 1 to use a little Radio Shack
contact
cleaner on the interior switches. On my Nav radio I noticed a bank of
rotary resistors (guess they are resistors since they are labeled R1, R2
etc.) and I am tempted to treat them and turn the pots back and forth a
bit
to make sure they're clean. Does anyone know if they are too position
sensitive to set back into their original positions by eyeball? Any other
comments about using or not using contact cleaner are also welcome.
Thanks.

PLEASE don't mess with ANY internal adjustments!!! Their operation may be
interdependent and, once moved, may be a bitch to properly realign. Don't
use contact cleaner on ANY internal components, or on any external plastic
components. About its only use by a lay person should be on contacts on the
slide-in connectors at the back of the unit.
