Philco Safari Vertical Foldover issue

Are there any specific resistors I should check the values on? Specifically those that may affect the vertical height or linearity?

Thanks again for your help.

R75-R80 would be prime suspects, but I'd check every vertical resistor (including the pots), and the synch resistors (since the bias of the synch sep affects current flow through the vert osc transformer primary and the osc stage).

Voltage differences (and if you have an oscilloscope, waveform differences) in the vertical stage should help you localize the problem
