Hi all: I have several more questions on my Philco 90 restoration. First I will say that the schematics for this radio are one of the worst I have seen and I have restored about 30 radios, mostly Zenith and Silvertone.
My radio is an early one with a cabinet date of April 27,1931 and a SN of 071645.
First question: Between part baloons # 4 and # 5 on the top line it shows them connected and both continuing to the grid of the 24 tube. My radio wiring shows no connection between these here. I don't believe the sch. is correct.
Second Question: Baloon 46 the bakelite block condenser is listed as part #5215 (.oo1mf). The installed part number on my radio is #3903J which is a .01mf condenser. Shoul I use the .001mf as listed for a replacement or the .01mf which was installed in the radio?
I would appreciate any help. Thanks.
Scott
