Hi,
I'm working on a Philco 48-1256 radio/phono. Years ago someone replaced all the electrolytics (which then failed) with what looks like whatever they had on hand.
I need to know the voltage specs of the 40MF (C103A) and10MF (C103B). The combined C103 is part number 30-2575-12 but Rider's doesn't give any voltage values for the capacitors in the parts list. Also if possible, the voltage specs for two 15 MF electrolytics (C101 and 102). Schematic is in Rider's 18.
What is in there now is a dual 50MF rated at 150V for C103. Two unreadable electrolytics were put in for C101 and C102. These all come off the 50X6 rectifier tube

Thanks,
Mark
