I'm working on a Mopar 921HR radio, from a 1957 Chrysler; Philco chassis C-5709. Does anyone have the original Philco service data for this thing? I need to repair the tuning mechanism, as the drive is slipping; I have the Sams manual which covers that model, but it has nothing on the tuner. I have already changed the audio output transistor and emittter resistor, and it does play.

Thanks, Greg! The factory data is a bit more complete than the Sams.
