Sorry 1 pin should show a short to the + side of 91 and the other a short to the + side of 43A. That's where the fc connects. The other two are the vc.
The diagram is not drawn properly it looks like plate and fc connection are connected thru the plug but they aren't. I wouldn't know this except I have a 41-300 which the same set up. OBTW check the resistance from the screen grid to the plates of the 41's to see if the pri is good. Sometimes 1/2 or both sides are open.

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!
