Model 70 Detector Coil/Transformer
#9

Additional request.
I have a defective Detector Transformer with an open Primary. The Philco website, under Techniques say the RF Transformer Primary should be 69 Turns of #32AWG.
On My Detector, I agree with the 69 turns, but the wire is much smaller, maybe #38 or #39AWG. I can't verify because I couldn't get more than 12" of continuous wire on the defective winding, it was so brittle.
The schematics do not list resistance for any of the windings on this Model. I haven't gotten to the Oscillator Coil, but highly anticipate the small outer winding will also be open.
Does anyone have information on what Gauge wire, or resistance for the Detector and Oscillator Coils should be?
My Caliper isn't real accurate at these small diameters, but #38 seems to be about right, and I have that, don't have #39 or #40AWG.
The Philco Part#'s are 03083 & 03084.
Thanks in advance for any assistance!

Thanks
John N3MUN
