Good that you are making progress. I've been reading your posts but haven't had a chance to dig out my 71 schematics and make an intelligent comment.

That reminds me, I still have to look inside the chassis of my 118B and find the shunt resistor for the shadowmeter so I can tell GlennPR where it is located. It isn't shown in the under-chassis diagram. Nice of Philco to occasionally leave out a detail or three here and there, eh?

By the way, the new cone on the speaker looks great. Two thumbs up to Hank Brazeal.

That's strange, it's shown on the under chassis diagram I have for a Canadian Philco 3118. It's basically a porcelain tube with wire wrapped around it mounted in a threaded rod roughly legthwise in the center of the chasis, the reason I know about it is that mine is open. Now if only I could find a 9'' Philco speaker for my 3118, I think it's a K7 type.
