John,
Very impressive performance from TT-42.

Steve, Dave, all,

I'm glad to hear your back to coiling Dave.

A little tricky to insulate a 15/60 Magnetek (Jefferson) after depotting,
but not really that hard.  I slid the outer core assembly (a few
laminations at a time) off of the center core, then cleaned away
the old mica insulation.  Then
I assembled the core with coils, and bent some 0.060" polyethylene
sheets into a "U" shape and inserted them between the core and
secondary winding coils.  I did the same thing with the Jefferson
12/30 NST in my TT-42 TC.  These pieces of poly insulation can
be seen in the TT-42TC NST at my webpage at:

at the bottom of the page.

Cheers,
John
