Philco 81 Questions
#41

Ocillator Coil on model 81.

My problem is that I am showing continuity from pin #1 first pin from left side of the ground terminal to pin #2 about 3.2 and continuity from pin #1 to pin #4 ,5.5 Now I also have continuity from pin #2 to pin #4 2.8 Is it possible to have three terminals show continuity. I have not rewound the primary winding yet because I do not know which terminals the two ends come out on. They were gone when I unwound the wire which was all corroded. I do know that the first teminal to the left of ground goes to oscillator. 2nd terminal goes to a trimmer top terminal at chassis. Third terminal goes to tube 77 pin 5 of that tube. From terminal 3, it has a resistor to span to terminal 5. Terminal 4 on oscillator coil has a wire going to another trimmer bottom lug.. I just don't know where the primary coil wires go.
