[Milsurplus] FS AM6155/GRT-22

[D C *Mac* Macdonald]

Not quite totally accurate.
 
The AM-6155 is UHF only and goes with AN/GRT-22.
The AM-6154 is VHF only and goes with AN/GRT-21
 
Many, if not most, of the parts are interchangeable,
but some tuning parts are totally different.  Also,
many of the components on the tube socket are also
different.
 
In amateur SSB service, these amps are capable of
close to 1 kW PEP input.
 
The FAA shop in Oklahoma City where I work overhauls
the GRR and GRT equipment down to component level.
 
I have enclosed corrections to factual errors in
