I would like to say something about 1950's vintage radios that are made on printed circuit boards and use the AA5 tube formula. I just restored a RCA 8-X-5. The hard part was finding all the "cracked" solder joints. They are very hard to find and hide very well. That old phenolic board material flexes a lot and the more it's moved the more the joints crack. The traces also don't adhere to board when they get old so I had to use a few hard wires piont to point. I think I would rather do the old rats nest wiring and a good iron. Just wanted to let every one know what to look out for when working on these early PCB types.

Actually, I think the worst two were RCA, and, GE for their PCB boards. Personally, I hate the things.
