So I'm just curious guys..... If you got a radio that works fine, is there a way to determine that everything is fine in terms of the enternals, or is it a must to just go ahead and replace everything as far as the caps go......

Personally not matter how well a set works, I refuse to play/use it with the original caps/electrolytics. I even go as far as to replace the micas you find in these sets. I leave no cap unturned I then move on to resistors and check any that carry sizable voltage and/or load. You never know how many hours they've played and how many parts were out of tolerance, causing undo load and heat. If the set played fairly well I leave tube checking for last. After a good couple hours of warm up, I then hit them on the tube tester.
