The grid/Cathode bias does change with range selection; I just measured
it. There doesn't seem anything obviously amiss with the readings:
If you've eliminated other faults as possible then time to adjust the bias on the iffy range.
There is NO adjusting the bias. It's NOT adjustable.
The difference in readings is based on the difference in output for
each range. It's entirely likely it was like that new from the
factory.
