The hum is probably normal. I just fired up a Crosley 66TC yesterday and it had a PS hum, constant, but not noticeable over any level of audio except almost-off.

I would not mess with it. They did as good as they could with low value caps and that is the historic result. Anything less would be modified.

It has other audio issues. Ron has discussed them a lot and a change to the detector you could also do, but I would not.
