G07 Vertical issue

Yep..tried all of em.. The vertical hold will actually lock the signal in two different positions... Im thinking the vertical oscillator is running at like 45 hertz or something like that..
 
Yep..Im pretty sure this is a monitor issue. I swapped to a known good chassis, and it worked fine, so same tube, and gameboard, but different G07 Chassis works fine.
 
Check your vertical deflection transistors, your vert size pot, your vert lin pot, your IC, and FR401. After all that, start going through your vert deflection circuit. Something is messed up there - possibly even a resistor that is no longer it's proper value...
