On v1 pins 1&3 are 15v and pin 2 7.25v it’s like the tube is locked on full pulling the 132v down to 63v. So I lifted the power on pin 8 it’s not the tube pulling the voltage down pulling the 8.2k ground drops the voltage. Then with the ground off I get the proper ohms.

Hi!
Sorry, Our crappy internet service was off for several days.... If you have 15V
on the Cathode of tube V1, 6EH7 the 1St Video IF, then I would be wondering
what the plate voltage is? is the 275V source right, and is it 275V or lower?
Also what id the voltages on each side of R38, a 22 Ohm, R44, a 47 Ohm,
and R45, a 560 Ohm. Also what voltages are on both sides of R37, a 2.2K Ohm?
Please make these readings with everything hooked up.
Also are your power supply voltages back to what they should be?
