[Boatanchors] National 6 pin coil forms

[Sandy]

This is correct!  There was no 6 pin  tube base yet when the 6 pin National 
coil forms were made for the first time.  If I can remember where I dug this 
up (two places, by two different writers) I'll post it.

73,

I remember BUYING some forms direct from National (they still had them!) who 
also supplied me coil winding info back in the late 50's when I had an 
AC-SW-3 complete with ALL the bandspread coils (Some I wound) and several 
general coverage coil sets.  This was the one with two '58's and a '27. 
Eventually, I disconnected the 2.5 v heater supply in the "doghouse" and 
added a small 6.3 volt transformer.  Then you can plug in 6D6's and a '76 
which were MUCH more plentiful!
