'57 radio and clock.

I have been debugging my 57 Bel Air and the Radio seems to be dead(no buzz when I turn it on) and the clock doesn't work either. Is there a way to troubleshoot it while it's in the dash? Paul

I'd start by first checking to make sure you're getting power to the radio and clock, then making sure they're both grounded to the body. The clock should be powered constantly, and the radio only when the key is on.
