I removed the power / tone control in the hopes i could fix it. I carefully pried back the four tabs holding the AC switch portion on. I tried a few rounds of DeOxit. but it just wasn't helping.
So I drilled out the two small brass rivets to reveal some very corroded contacts. I buffed them using a toothpick and Simichrome then flushed it clean with more DeOxit. That did the trick
I didn't have any small rivets on hand so used some small brass tubing. I bent and flattened one end, fed it through and mushed the other end. Finally, I reattached it to the main body and bent the four tabs back. I wired it back into the radio and it's working like a charm.
