I couldn't find 81 either. But it's listed on the parts list and it's outlined on the under the chassis diagram under the tuning cap.
As for the schematic you gotta work with what you can get. The used the one in the library. Sometimes the service bulletins are better but we don't have that one. Maybe Andy has it and it's yet to be added to are files.
>Why is it still humming? There's a whole lot of possibilities. The short answer is there's ac getting somewhere it's not suppose to be. How are the dc voltages? Across the filter caps and plate and screen grid voltage on the output tube?
OBTW ru going to grace us with ur presence @ the town of K?

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!
