For a radio of that vintage and specially one not used very much........it is
time to clean connectors. A radio that sits and is not used much, one is not
saving it but actually allows it to deteriorate.
Unplug each cable one at a time. Wipe the male pins using a Q-Tip moistened
with contact cleaner. Then plug and unplug a couple of times to wipe the female
contacts. Be sure all connectors are correctly aligned and fully inserted.
NEVER spray anything into the radio.
