Model 70 Detector Coil/Transformer
#1

This is my first attempt at fixing this, so go easy on me! Icon_smile 
The Primary winding is open, and according to the schematic it is Part# 03083. one of the wires was broken near the solder terminal, but there must be another, or more breaks elsewhere. So I plan to rewind the primary.
I found in the Library the "Rewinding Philco Coils" information, which is a big help, but I want to confirm some information.
The links to the www.philcorepairbench.com don't appear to work, and I tried going directly there, and no luck either. It looks like there should be 69 turns of #32AWG for the primary. I can try to count the turns when I remove the existing winding to confirm. It looks like there are 2 layers of windings for the Primary. If so, I think there are more than 69 turns, but I will check that and plan to use the same number of turns as the original.
I don't have any #32, but I do have #34. Would that be OK, or is it critical to use #32?
Anything else I need to be aware of? I know direction of the wrap is important.
What do most people use when finished to help keep the windings in-place? I think it used a wax originally.
Thanks in advance!
