Yep! Good point. In the HV position, not shunt resistors. Of course,
easier to say then "check the resistors in the meter circuit that make
the HV scale read acccurately".
I probably should check mine. I haven't looked at them in 36 years. Maybe
I should change the tubes too. They're still original.
