Philco 90 Help Needed
#14

I have the single output version of this radio. I agree that there seem to be a lot of errors or changes in the schematic (I've ordered Chuck Schwark's nice schematic sets, this should help me figure out some things). For instance, the can caps don't match what is in the parts list. Using the part numbers listed, and looking up the information on Chuck's site, the capacitor values are different than listed in the list next to that part number. Some of the bakelite blocks differ from what is listed in the parts list as well, but this may have been due to production run changes. The good news is, as I have replace various parts as listed on Chuck's site, the performance of the radio has become more and more phenomenal.
