[Paul Christensen]

Al,

 

See the part where it says…

 

“We are also selling the special coil form for the National Radio SW3 and SW5.’

The National 6 pin configuration for coils used in the SW-3 is NOT the same as what 6 pin tubes used which is what appears offered on that Atlantic site.

See link below for a choice of 4, 5, or 6 pin forms, constructed much like

Not exactly inexpensive if building a full coil set, but there they are.
