[AMPS] SB-220

[R_Davis]

Then why do some amplifiers'  manuals tell you to monitor the grid current
and give you a meter function for that purpose?

?  Monitoring grid current is of zero value because tune-up has nothing
to do with grid current.  Tune-up involves tuning for max out with max
drive (<145w-pep) using a tuning pulser or a keyer sending dits at 50wpm.
 Thus, only a relative RF output meter is needed for tuneup.
