Hi Kent
Well... my radio player started coming on at random times of the day, including in the middle of the night, starting a couple of weeks ago. I tracked down the problem to the potentiometer, which no longer had a minimal resistance at the start position, and the resistance was generally wandering at particular dial positions. I got the potentiometer in a box of "starter" components, so I don't think it was a good one! I swapped in a new potentiometer from a batch I bought, and the radio is now working well again. The dial gets turned several times per day, so it does see some action.
