I got home from work today and all the ladies were out and about, so I took the opportunity to do some troubleshooting. I shut off all the 120V circuit breakers for the house and ran an extension cord to my radio from the garage. Then I turned on the circuits one at a time until the noise came back. That narrowed down the noisemaker to one area of the house. Then I started pulling plugs in that room until the noise stopped. That unmasked the culprit: an audio amp/speaker set we use for the TV. It's probably got some bad electrolytics. I'll see if it can be fixed this coming weekend.

That is a load off of my mind. I was afraid I was going to have to pull the chassis out of the radio again. Icon_smile
It's not how bad you mess up, it's how well you can recover.
