now on to my difficult questions.

see picture
Q- to the left is code 122 prints and at no point is the on off switch tied to my rectifer tube.
In the real world, i have what is hand sketched to the right.
I did some reading and saw people talking about how to bypass the primary of the power xfrmr when it craps out.
Does it appear this mod was done here?

I found this in my 47-1230 as well.  They used pin 8 of the 5Y3GT socket just for a terminal.  There is no internal connection to the tube itself.
