Sorry I don't know what you mean when you say test a positive lead to a negative, but someone on this forum a while back told me that when I test tube voltages, it's in respect to the cathode. In other words, he said, use the black wire on the multimeter and touch the cathode instead of the chassis. So, I tested all the pins with the black test lead on the cathode, pin 6. Hope this helps. Sorry my terminology is not great, but I appreciate you hanging in there with me.

pin 1=3 volts
pin 2=12 volts <--- Plate should be about 260 ??
pin 3 = 85 volts
pin 4 = 212 volts
pin 5 = 10 volts
pin 6 = cathode 7 volts to ground
pin 7 = 3 volts.

Thanks !!!
