Pull the Tuner unit out. Get some "DE-OXIT" D-5 @ Guitar center. With the power OFF and the plug pulled out from the wall, spray the De-Oxit into all the pots', and switch contacts. Rotate all the pots 50 or more times, then cycle each switch the same.
This will clean most all of the oxidation that has accumulated on the switch and pot wipers and ensure a clean contact. This may or may not rectify your problem but WILL Eliminate dirty contacts from the troubleshooting list. Also with the unit being OVER 40 years old, the capacitors will more than likely (>90%) be dried out and causing drop outs, opens and shorts in the circuits.
