Well, get a DMM. It will measure higher voltages than the old-style voltmeter but understasnding the fact it does not load the circuitry one could extrapolate the new reading and relate it to the old one that is listed in the voltage chart.

In any case if you see 0V where you should see 100V is a red enough flag so you do not have to wonder about 10-30V difference.

Also, you did not metion if you replaced the out-of-spec resistors.
