So guess what's back on the bench??
I had it back together and playing well but it did have a few bad habits that need some looking into. I made the ultimate decision to install a Philco speaker plug and socket. On the tombstone sets with the 10" spkr the top lip of the basket fits into a narrow cove at the top front edge of the cabinet. Both of the cabinets I have were close to firewood and the tops were apart. Now it could have been when I rebuilt the cabinet I didn't realize that was an important gap. Meaning that I might have clamped the top center section a little too tight so fitting the speaker is a little difficult. Add to that having the chassis hanging half in and half out of the cabinet makes it a bit of a chore.
I scared up the spares to make the improvement to find a couple of things. It's not a drop in replacement. The mounting holes in the socket are about 3/16" further apart vs the holes in the chassis. Do to the position of the mounting holes the flat on the plug will be on a diagonal vs parallel to the bottom edge of the chassis unless you redrill them.
As for the wiring from what I can tell a number of the P/P speakers have the same wiring. This would include 116X, 116B, 660, 200X, and 201X. So if you look at the socket and start with small pin. Call it #1 it's one of the 42's plate connection. In Philco speak it the white wire. Going clockwise #2 connects to the field coil/center tap of the output transformer. White/green wire. #3 connects to the lone field coil connection. White/blue wire. #4 connects to the other 42 plate. Green wire.
I would love to say I plugged it in and it worked dandy! But this **** thing has a rebellious mind of it's own and has developed a short in the hv line. The good new is I think I've come up with a couple more solutions for the lo problem. More later.

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.

Now I think I've got!
