Re: 1954 Radio not working

Oftentimes the issue with the radio come down to one of two things:

1) The capacitors degrade/leak. Those can be replaced.

2) The "vibrator" degrades, this is the thing that "hums", it turns DC into AC so signals can be amplified. Sometimes those can be "revived", sometimes they have to be replaced. These look like tubes and can be replaced either by a solid-state version or a NOS electro-mechanical.

3) The power tubes can go out as well, those were available for my 1953, they are probably available for your 1954. You might be able to find one of those tube-testers somewhere, or they can be tested yourself with basic equipment including a DC power supply.

Vibrator Look Up (have to navigate over the "Radio Vibrators" subsection on the left), yours is a 1015-P.

Here's a solid state vibrator, make sure to get Positive Ground. I bought one as a backup to my rejuvenated electro-mechanical vibrator.

Solid State Vibrator

An interesting solid-state vibrator board you can install into your existing vibrator can:

If you look at the Factory Parts list to the left, there are 4 radios shown for 1954, PA439661, PA439665, PA4395663, and PA43966.

I remember buying a radio diagram from these guys for my 1953https://autoradioschematics.com

But it doesn't look like they have yours listed, though they say they have 1000's more.

However, I found the schematic here:
