Thanks Keith! Philco and their numbers. Yours is correct being a 10ufd (probably 450V) filter cap on the B+ line with the 300 something ohm wirewound #35 I think, resistor. But this is a car radio and all of the filter caps are in a can on the dynamotor housing. No filter caps on this chassis. I've identified all cap can values (less this one) and none of them are lytics.

And there would be no reason for a 10ufd lytic filter cap on the cathode of the 85 2nd detector in this radio. Maybe a 1ufd or 2ufd @ 25 volts. I'm just not sure. My Riders paperwork calls it out as part #7774. What is the asterisk next to the part number on your 10ufd for? Possibly some note?

Like I said... Philco and their numbers. I'm hoping the paperwork from Chuck S. will shed more light on this. Maybe later someone else will chime in and know for sure.

Thanks,
Pepperoni
