::Hey, all. Looking for some ideas about a problem with this radio. Sometimes (but not every time) after it has been on for a couple of minutes or longer, the volume will start to drop until there is just a hum. After a few minutes, the volume slowly comes back up and the radio plays normally. I was hoping that the problem would worsen so that it would be easier to locate. I hate intermittent problems like this. I have replaced various resistors, paper caps, and the electrolytics in previous repairs. Any thoughts about what to look at first? Mark from Kalamazoo


Mark:
Are you married? If so, does your wife have a hair dryer? Do you have a Radio Shack nearby? If so, do they have cooling spray? Assemble the preceeding while study the schematic and we'll get together later.
