I know; I was just speculating on how he might have blown it up. I had one
for years, and connected it across the meters of several transmitters, some
tube, some solid state. I also used it with a Heathkit VTVM which could
read up to 1500 volts, and I never came close to blowing it up. I think the
instructions had some caution about taking care not to ground either side of
the input, or having too high a voltage between the input terminals, but I
may have read that somewhere else.
