I started working on an Atwater Kent 55F table radio. The F is a radio designed for 25 cycle AC rather than 60 cycle. Hopefully it will also work on 60 cycle.
I got the Filter Capacitor can open and was quite impressed with the workmanship. It was potted in some sort of white wax that was quite easy to remove. Unfortunately, I'm not as impressed with the potted transformers. Once again I'm faced with an open winding in one of the transformers. This time it's the secondary of the audio driver transformer. Both the driver and output transformers are potted in the same can with a very hard tar like substance. It is going to be a very great pain in the behind!
Since there is a fair amount of mouse urine damage to the chassis, I'm going to have to use paint. I'll probably remove all of the transformers so I can do a better job of cleanup. I think this will be the most work yet as I learn this restoration hobby.
There is a loose, very heavy cup shaped device with a small hole in the top. From what I've been able to gather, this is a tub shield for either the detector or 1st audio driver. It would appear to just sit on top of the tube. Any knowledge out there as to it's purpose and it's weight? Is the mass there to help dampen vibrations on the tube ?
