91-221 coils
#1

schematic:  http://www.nostalgiaair.org/pagesbymodel...013884.pdf



I'm hoping to get some guidance on coils, specifically, the antenna/RF coil, #2.

I've yet to rewind one, but have watched a lot of Youtube about it.

Mine has an open inner primary (the antenna side).

Schematic shows it should have resistance of 24 ohms.



It's not an outer, smaller winding over a larger winding, like I've seen in various posts/videos.

It's like a bobbin inside the tube at the opposite end from the terminals.




If anyone can tell me what my next step is, I's sure appreciate it.

Thanks.
