Hi Fred
When they first came out with the FET volt meters, they called them
solid state VTVM's. Of course this doesn't make sense but they were
only trying to indicate that these had the higher input resistance similar
to a vacuum tube input.
It was just marketing.

On this (semi) subject, I vividly remember for a
while seeing a
"solid state VTVM" that had the extremely high input impedance
of a VTVM/DMM +
sounds nice
but what is a "solid state vacuum tube" volt meter ???
