Update on 38-5 restoration, Almost ready for cabinet!
#3

I think if it where mine and I was going to use the table top cabinet I would use a PM spkr and do away with FC. The main problem is that for the most part the K style spkrs are used lower tube count sets (table top set) There area few exceptions but the FC in a ten tube set is going to be able more current that a 6tuber with the same resistance. More current means more magnetism, conversely you could use a ten tube set's spkr in replacement on a six tube set but there may not be enough current flow to generate the full amount of magnetism to run the spkr properly.

The console's opt is usable with a PM spkr although not a perfect match. Most of the older Philco VC impedance is around 1 3/4 ohms, modern spkr are 3-4 ohms. Not too much to loose any sleep over.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
