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
Starting on the alignment. Looks like the 455khz crystal has drifted to 452.6khz. The alignment will correct for the drift. The drift is normal, due to the age of the crystal. 65 years and counting
