Hello everyone. I have been restoring my Philco 19B and documenting on ARF.
I've been chasing down an intermittent and challenging issue with periodic and temporary volume drops. I finally found the likely cause today, an open antenna transformer primary in which the broken wire was making intermittent contact to the outside of the coil. The coil looks to be charred from lightning damage.
The entire transformer is part number 32-1062.
I am considering rewinding the primary or replacing with a compatible substitute. Does anyone know how many turns the primary should have? I do have 40 AWG magnet wire left over from raining the shadow meter coil.
Thanks!
