sams and RCA service man both show about -55v bias on the vert osc output grid, of course they show diff voltages for the grid and cathode but both net to about -55.
The sams shows a 38ma current thru the cathode, no way to read that directly but I guess I could determine it based on the V drop across the cathode resistor..
hmmm scratch that not that simple, I was reading something wrong. This would be a nice time to have a test socket that you could jumper each pin on or off.
not a tube extender but a tube extender that you could make/break the pins for current readings. I dont know if such a think exist.
