Good morning all
I've been working on the 321 lately and am having some success.
Work done so far: replaced paper caps, replaced 2 section electrolytic, replaced one resistor, replaced power cord.
All voltages are good and I have good reception with a long wire antenna, though the sound is a garbled. I am pleased with the recepton, and I listened to several stations last night. However ...
I have volume with no volume control, if that makes sense. When the radio starts working, volume appears to be at a preset level with no change as I turn the knob. A slight twitst of the knob yields a little more volume but only for a moment. I feel that I have a dirty or bad on/off/volume control switch. Question: Can I spray contact cleaner into the switch without causing damage? I really don't want to take that thing apart! From what I have read on the Phorum, a bad switch can cause poor reception.
Thanks,
Terry
