Please help with the Philco 71B, my first time trouble shooting.
#9

I think I found a break in one of the winding on the OSC coil after tracing the 36 K to ones section of the coil. According to the schematic that lug section that the K goes to ends up coming out of the center bottom lug that goes to R18 and C19. The only problem is that I get no continuity between both and when I Ohm it out the reading is in the Meg Ohm where as the other winding in the coil that have continuity test in the 3 or 4 ohm range.

Here is a diagram below to show what I mean. Thanks

Does anybody out there rewind coils, particularity this Osc one.

Jon
