National NC-60-Special
#3

I continued to work on the NC-60-special. All the tubes tested good, which was a pleasant surprise. I spent a great deal of time loosening up the tuning condensers, both the main and bandspread, as well as both the dial slide mechanisms. This radio must have sat in a damp place for some years. It took a lot of working back and forth with my oil mixture on the bearing points of the condensers and sandpapering the slides and pointer slider insides, and lightly lubricating the slides. Finally have the tuning working nicely. I also replaced all the paper and ceramic disc condensers. I am waiting on 200 volt 40 MFD condensers to finish up the under chassis work, then there will only be the alignment.

Here is the underside of the chassis at the beginning of work. I had only removed the rivet holding the multi section "firecracker."

This is after all the work so far. I'm just waiting for the 3 40 MFD 200 volt electrolytics to finish. They will go on the terminal strip on the right side.
