With winter here I am getting bored and need a project. I decided to try to tackle the radio. The furthest I got with the radio in the '51 was to lube/free up the station preset buttons. You can view this on the '51 blog here.
I pulled the '51 radio out and tried it on my 6v battery. The dial lights up, two tubes have a dim glow on top and I hear a humming noise. Nothing changes with the volume or station selector.
Before the snow hit, I pulled the '52 radio from the car. It did not function but it turns out it was not connected. I hooked it to the 6v battery. The dial would light but that was it.
I opened both radios up and removed the vibrator from the '51 and put it in the '52. Now I had a hum, but no changes with volume or station selector. Looks like the vibrator in the '52 is toast.
I have spent a lot of time on old radio websites looking for help as to what could be wrong. Seems like the capacitors dry out and stop functioning after all of these years. They recommend you replace all of the capacitors. They make it sound easy, but having extremely limited soldering experience and zero knowledge about electronics, I'm sure it is harder than they say.
Between the two radios, I decided to try to get the '51 going first since it made a static noise when I first got the car before quitting.
I removed the guts from the housing. The things I think are capacitors look gross! Melted wax look. Now I need to buy the right ones. The radio diagram on this site looks helpful. I also found the attached PDF on nostalgiaair.org as a free download. It was hidden under United Motors Service - Delco as the manufacturer. The PDF link is right below the third picture.
After exposing the top of the radio, I can see there is not a lot of room for swapping out the capacitors. Makes me a little nervous, but then again, I have a spare radio I can send out for repair if all of this goes south. So far, I have noticed a capacitor with a broken connection which could be the whole problem, but I need to replace them anyway.
