I traced every connection from each V9 pin until I ran into a different tube or other stopper, but I found no errors.
BUT!! As I was pondering cutting the coil in a resistor-through-coil to check the resistor, I also pondered Notimetolooz's mention that the contrast controlled the voltage. When reading the voltages, my contrast was set at the max. Although the instructions were to set the controls at the midpoint, I only set the rear controls. My bad. Voltage at V9 pin 6 varied with contrast from 56V to126V, and V9 pin 5 varies to a much lesser degree. Setting the contrast control at the approximate midpoint, pin 5 was 142V and pin 6 was 118V. Ta dah!
It's no solution, but at least that low voltage can be ruled out as a symptom of the problem.
