Schematic shows a volume control w/4 connections (2meg w/a tap at 1meg) On the other hand the tone control has 3 connections. Maybe your vc was replaced too.
When my pals were reading comic books
I was down in the basement in my dad's

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!
