Hi, have a look to Jeff's museum pages, lots of stuff there on pancake coils
at
www.electrotherapymuseum.com/  jeff has made many pancake coils. cul brian

I use a cylindrical primary, would that mean that the secondary needs to be
a few inches above the middle of the primary?

Better yet, is a pancake the best primary form to build?

Thank you.
