Hi Terry,
I removed the 1st detector Philco ( part number 03015) coil from the model 90 . This allowed me to validate that the primary winding was not just broken at the solder end. Unfortunately, I still get an open winding. You mentioned about 20 -30 turns, but I can see there are a lot more than that.
Do you have any idea where I can get a coil. Hopefully, would like to find some one who sells new old stock. As the wire gage, resistance of the coil, and the inductance are not stated, I really don't feel comfortable rewinding the coil.
I am also missing the larger shield mounting bracket which at some point in time must have broken off. If I leave the shield off, I am concerned I might well end up with motor boating.
Thanks for your help.
