I'm wondering if it isn't a bad Horiz Frequency coil (B2).
It's grounded at one end, the center tap goes to the cathode on pin 8, and the other end is connected to pin 5 through the .0047 cap, then to a 27k resistor then to ground through the 50k hold pot.
The plate (pin 8) has over 400 volts on it, pin 3 starts out over 300 but drops to 140 as the tube warms up and starts to conduct.
Just did a few more checks.
The Horizontal Phase coil is equal on either side of the center tap, about 36 ohms, however the horizontal frequency coil is about 50 ohms on one side and 20 on the other, not sure how that could happen exactly, overall it measures in the ballpark.
