Got another radio on the bench. National NC-98. Initial inspection... Overall its clean and not corroded. Lots of dust. Wrong rectifier tube. Rectifier tube glass feels loose, and may be broken. All but 3 if the tubes look to be original Tung-Sol. Bottom plate missing. All original capacitors. One capacitor disconnected and has yellow electrical tape on it. One trimmer capacitor is completely broken in half and will need to be replaced. It'll be a challenge but I think I can fix it
This radio uses two 6BD6 tubes. Both tested weak. These tubes are fairly rare, and believe it or not I didn't have a single one in my collection. However I found that the 5749 tube is a substitute, and I had several of those. The two I picked out measured excellent and above spec.
