If the radio was going to look good, something would have to be done with the scratched cabinet.

I contemplated painting it but decided to sand and polish it first to see how it would come out.
 
When the plastic is scratched or dinged it turns light blue.
 
Sanding out the scratches and dings. Ironically, sanding it was scratching it a million times more.
 

The sides and top were wet sanded with 800, 1000 and 1200 grit sandpaper in the kitchen sink, then polished on a buffing wheel, then polished again by hand with plastic polish. After that, it was given a coat of automobile paste wax and buffed. Not every single imperfection came out, but it looks almost new. For all I know, it looks better than when it was new.

 

 
 
 

The front was masked so the plastic part could be cleaned and polished. I put a lot of thought into how I would remove the clear plastic film. When I removed the masking tape, the clear plastic came with it! Under it was a pristine front panel. Problem solved. Good thing I WANTED it to come off. What if I didn't?


 

The only evidence that this front panel is 50 years old are some tiny dings in the plastic grill and the top of the aluminum faceplate.


 
 
Whatever had been sprayed on the grill came completely off, and all the dirt on the faceplate came off with the plastic.
 
 
 

Next, the back was given two heavy coats of spray lacquer to arrest the shredding of the material. Man, it soaked that lacquer up like a sponge! The tabs on the bottom had become frayed over the years, and the ends looked like little puff balls. They were soaked in white glue, then covered with wax paper and held in a clamp overnight.
 


 

I didn't know why only a single band was working, but I saw on the schematic that the short wave bands all go through a very small value capacitor. The three capacitors were replaced. Also replaced was capacitor C16, at the very top of the schematic. C16 is for the AM broadcast band.

 
 
 

C13, C14 and C15. These are what the arrows are pointing to on the schematic. They were replaced with high quality silver-mica capacitors.

 
All of the electrolytic capacitors were replaced, as well as the transistor that had been pushed through the board, lifting the copper trace on the other side (previous page). The capacitors all tested good, but about 20% higher than they should have. The transistor was good, too.

About a half dozen poor connections were resoldered. When the radio was tested, all four bands now worked. So what fixed it? Beats me. I suspect it was re-heating those poor solder connections.

Replacing the 50 year old components helped. Those old electrolytics had to come out anyway, and the silver-mica capacitors probably have it working better than new.

There was one problem when the radio was done. When it came time to put the circuit board into the cabinet, the screws wouldn't fit! (Three of them are visible above, along the bottom of the board.) They seemed to be too long. No matter how tight they were, the circuit board was loose. 1/8" of the tip of each screw was cut off to shorten them.
