no.  The hat trick is tuning up.  One must tune up the linear amp. at 4x 
the carrier P.- or 140w in this instance.  With most ssb amps, it is best 
to tune up with pulses (50wpm dits or a tuning pulser) to avoid 
overloading the hv supply.  //   Setting the mic. gain is not as 
straightforward as with ssb since the anode/plate meter is steady and 
does not indicate modulation level.  A pep wattmeter is more useful.  
More mic. gain is not mo' betta.  .

For maintaining a reasonable S/N ratio at the receiving end, AM consumes 
more electricity and generates more heat than does SSB.  
-  Another disadvantage of AM is that operators tend to make moderately 
boring, ten minute lock-to-talk soliloquies instead of engaging in 
ordinary conversation.  When I operate AM, I operate high speed VOX -- 
which drives AMers up the wall.
