[Amps] New Ameritron AL-80B Tune Up

[TexasRF at aol.com]

Thomas, you can save a lot of thermal stress on the tube and other parts by 
 tuning with high speed cw dots instead of a steady carrier. Most radios 
now have  cw keyers built in so you can easily do that.
 
With a dot to space ratio of one, the meter readings will be about half and 
 the heating will be about half as well.
 
Many of us don't even use ALC; we adjust the drive level manually while  
watching grid current.

I  purchased a new Ameritron AL-80B and the manual is not totally clear to 
me  
as far as tuning it up without damaging the 3-500Z, especially how to set  
the ALC to prevent overdriving. Could someone that owns one please give me  
a 
basic guideline on how to safely tune the amp up?
