Philco 49-901 - Horrible (Garbled) Sound
#14

Glad you got it sorted out, Ron. It sounds great! This is an important lesson, and one that bears repeating:

"Lesson remembered: In an old AC/DC radio such as this that has obviously seen heavy use, don't stop at replacing the paper and electrolytic capacitors. Replace the old resistors as well, and mica caps as needed."

It had to have been one or more of those resistors / micas that was causing the garbled sound. Possibly the speaker was causing some of the distortion as well, but the main culprit had to have been one of those components. I had a Silvertone once that was dead. Would not receive any hint of a station (the output section was working fine). Turns out it was a mica cap that went south. Once I replaced that, the set came to life.
