Hi all,
I have come across some more information on these early Spellman's.
One power supply is using the "big" coil advertised on another page and is
the same one from previous pages I have posted. Pretty neat to see the
insides of this one. Quite a bit going on here.
I am still going through several large early trade catalogs that I have
aquired.
This catalog here is just a tad over 1500 pages.
I will let the pictures speak for themselves:

Not too much longer, I will be "tearing" into the one RFPS/DC that I
aquired.
