This one is a doozy- The sound goes out after anywhere from 5 minutes to 20 minutes. Both channels, radio or tape. The amp chip is new, and has plenty of gain at it's input even after it goes quiet. The VU meter stays the same, the radio still works quietly. Somewhere after the radio and tape audio output, but before the main amp, the signal is going out. This chassis uses printed resistors on the PC board, and many SMD transistors- but with no schematic, it might be a lost cause. Hope someone can help!

Forgot to mention- Freeze spray does not affect it. Once it goes out, it's out. Only turning it off a while brings it back...
