be sure that the cathode current on that tube is OK, otherwise much of the circuit
will be disturbed. Bye for now.

Yes, I'll definitely keep a watch on that. I'm seeing that the line from that staged supply is going to the vertical section as well... I wonder if these things are all interrelated - someone goofed and put in a 6v6 for the audio, and then thought "huh, the vertical is off" and the tech replaced the VBO transformer because the staged supply wasn't immediately obvious?
I have to look around some as none of my general use stuff measures impedance but I found a vintage meter amongst my things and I'm hoping that at the very least it is a VTVM... Very possibly I'm mistaken but I thought I saw impedance functions on it as well. I didn't give it a second thought at the time when I found it but now I'll have to dig it up again and see whether it might aid me in my restore.
