:Now, come on you guys! someone must have some ideas about where to start looking. Anyone? Mark from Kalamazoo
::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

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.
