I uploaded a pdf of the underside of the before chassis, which was very clean. When I started to work on this radio I took the time to understand the layout and added pin numbers etc. to the photo creating a useful map, similar to the original documentation. This pdf may help someone with their Model 20 restoration. Unfortunately, I didn't take any photos of the finised chassis. I will remove the chassis at some point and take a few pics to post here.

The main issue with this radio was the power transformer. The HV windings were open. So, I decided to disassemble the transformer and rewind it! I have attached a photo of the transformer after I removed the iron core. The rebuild of the transformer was successful! Looking back, I should have taken photos after rewinding, my bad.

I restored all of the tar filled condensers and the main power supply filter condensers. On this radio I learned how NOT to clean the dial scale! I had to get a reproduction.
