Philco 46-480 Power Supply
#3

Hi Joseph,

The C100 A and C100B are for RF suppression, to keep motor and switch noises from the radio. Yes, they should not pass DC, but I can attest from strong shocks that these caps leak and break down. These should be replaced with safety caps. Check other experts, but I would install a polarized cord with the neutral on the unswitched side of the transformer and the hot to the switch. Use an X Safety cap between neutral and chassis ground and a Y safety cap across the transformer on the switched side instead of between hot and ground. This is a change from the original circuit, but should be safer and just as effective. Alternatively, if you want to use the same circuit, use a 3 wire cord, but still move the "hot side" cap to the "load" side of the switch.

The 1A fuse is a very good idea.

The filter caps do not need to be safety caps; I don't even think that they make a Y type safety electrolytic but I may be wrong.
