OK, that's great information and thanks. Now this radio had incredible sensitivity on the standard broadcast band, but the shortwave is a bit lackluster, but is working. I would have to do what I call letting an old set "cook" for a few hours before I would do much of anything replacement wise.
I say that based on the fact that I have and always do bought the radio up to line potential slowly and it has already played well for a number of hours continuous with a cool electrolytic can and transformer. Or at least as cool as the two can be with a honking 5U4GB sitting between them which by the way may be replaced by a 5U4G that I have been saving for just the right set.
Anyway, It is safe to say that the radio's power supply is in good and safe condition and the rest of the circuitry pulling in Standard Broadcast through the AF stage are in working order. As far as "cooking" I am basically reforming caps on the fly. Most sets saw way more SB station selection than Shortwave. It may never have been used. I have found many times that simply letting it play at reduced current for two hours or more for a number of consecutive days can do the trick.
I have found this to work on very old TV sets too. There is a guy who sells what he calls restored radios on praybay. I think I have a 40s Radiola that came from him and it plays so good and was so clean that I still haven't pulled the chassis to see his work. Point being is that he claims to let a set play for days in his shop and then for a few days more in his living room (or something like that). It made me feel good about the purchase and the Radiola 6 tuber is a real treat to own. Perhaps common, the 40s RCA typical Bakelite table radios are very well built, good performing, but perhaps more utilitarian than our beloved Westinghouse models.
