I dont see the VOT going up in value. If you have access to
Sams collection find a similar chassis & see what it says
for an ohms reading. Also every VOT I remember changing
did not have otherwise "normal" vert, had small or no
sweep, bunching, pairing, retrace etc.........
Most size problems when otherwise normal are high ohm
resistors around the size control. If you dont nip off one
end to test they can fool you.
