Philco 37-660 Hum
#1

Finally got into working on this radio after a few years of ownership and letting it sit. Replaced Electrolytics - what a pain on the ones in the RF section!! I am now picking up stations very well but have a residual issue - low grade hum. This is not the obnoxious that existed before the original electro's were replaced but it is enough to be distracting. I have been going through replacing the other paper caps - and have not gotten into bakelites as of yet - could one of these be the culprits or is there something else I should be looking at?? Before I moved onto other projects I thought I'd look to the experts and see if I'm missing something that can bring this to a solid working state.
