I really don't understand why anyone feels the need to use a pulser for tuneup.
If your amp can't do full power for the few seconds needed for a tuneup, you're
pushing it too hard anyway, IMO.
It's not whether the amp can do a full power tune up, it's now much it
drags the HV down. Many of today's amps just don't have the HV
regulation to keep it up under a full load so the amp will be out of
tune for the higher SSB peaks, or even high speed CW at full power
unless the EI ratio remains the same.
