I did some voltage tests and found the +135V line is too high, at +173 volts. That points to a problem with the high-power three-section resistor in the compartment by the power transformer; the 6750-ohm section may be bad. That will be my next check. The video was mostly behaving as I did the tests, and the one time I caught it, the +173V went down to +171, so it may be a separate problem from the voltage issue.
