Just a word of caution - you should short the positive HV lead to the
negative HV lead, not to ground.  Most GG amps made in recent years do
not connect the negative HV lead to ground except for an "incidental"
connection through the grid current meter.  On an amp which does not
have protection diodes for the meter, you most likely will bend the
needle.
