If you take a quick gander it the schematic #49 (the can w one terminal ) the - side is grounded. But the can w/2 terminals #50 each terminal has the + side of 2 8uf 450v condensers to them. Both - connect to the shell which in turn connects the hv center tap. This how the -bias voltage is filtered which supplies the control grid of the 42 and 75 tubes. If you ground it there will be no bias voltage. Your 42 tube won't like you anymore and will probably produce some hum.

I guess I should answer your question more directly that would be yes and yes.

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!
