Philco 19B Open IF Trans??
#7

Confirmed- open winding on the 1st IF transformer. I think its the primary, but the wiring attaches to the secondary trimmer?? Anyway, its the winding that connects to B+ . Cant see any breaks when looking over the coil so it must be deeper. Very simple looking coil. Guess Im looking for a replacement or somewhere to have it rewound.
How critical is the accuracy of the winding?
Im thinking that any 1st IF trans from a Model 19 or 89 would work. 260KC with 56 ohms on the primary and 56 ohms on the secondary.
