Anyone have ideas here. I'm pretty sure the issue is with the 5gh8 horiz afc/osc tube. The voltages come of the 260v line and seem fine, but when looking at the schematic, I measure the other side of the 3.3 meg resistor the voltage is pulled down to -50v. I checked the two coils in the area and they measured fine. I have replaced the resistors and caps so I am not sure what would cause the voltage to be so low. Any ideas? I posted the relevant part of the schematic, but more of it is uploaded elsewhere in this thread.

Here are the voltages again
pin # sams what I measured
1 225v 224v
2 -.2v 3.5v
3 80v 38v
4 and 5 are filiment
6 140v 19v
7. 2.5v 4.3v
8 .1v .16v
9 60v -50v
