Philco 70 Cathedral Speaker
#35

I bought some 36 AWG magnet wire on Ebay. The wire arrived in a few days but, I have a problem, the insulation is much thicker. The original and the new wire both measure .005, stripped but, the original wire measures .0055 with the insulation on. The new wire measures .007 with the insulation. Well, I decided to go with it. The bobbin is about a quarter of an inch smaller than the poll frame so, I cut larger fiber discs and glued them on the ends of the bobbin so I could get more wire on the bobbin.

I made a simple winder and wound the coil.

I wound the bobbin as full as I could but, the resistance read 2450 ohms. I don't want to rewind the coil so, I may need to add a few hundred ohms resistance.

Now, I just need to recone the speaker.
