Model 70 Detector Coil/Transformer
#4

Just got back to preparing for the winding of the Primary for the 1st Detector Coil for the Model 70, P/N 03083. The information from the website in the Coil Winding Section is for the RF Coil, so it's NOT the same for the Detector. As close as I can tell, the Primary Detector Coil is #40AWG (~3 mil, as close as my caliper reads). Could be #41AWG, but that seems like an odd value. SO I also expect the 69 Turns to be incorrect also. I haven't unwound it yet to verify, but it looks like its more turns.
I can't work backwards using the resistance to confirm the gauge, since there are obviously breaks within the existing windings. And there is no data that I found on the resistance of the Primary Winding on this transformer.
Does anyone have information to confirm the correct wire size for the Primary coil, before I order the wire? OR am I splitting hairs and just go with the #40AWG?
Thanks in advance!
John

Thanks
