I was wondering what the advantges are of having B- on RF amplifer
instead of just grounding it? I think it may be that the plate meter
doesn't have a huge voltage across it, that can arc to ground. But what
if you are using a triode and just have a cathode meter, no plate meter
is the B- necessary? Any comments are appreciated.

What kind of circuit? Is the B- applied to the grid? What class of
operation? You mention meters so this is the final stage of a
transmitter?
