Rumour has it that it will do 800mA in SSB service.  However, I would be 
reluctant to go with a brick on the key test at more than 600mA.  Rumour 
also has it that the rated warmup is a bit on the low side.  An extra 
half minute might be worth the wait.  

In regards to FCC intervention:  IMO, this is unsliced bologna.  Tube 
specs are not part of FCC type acceptance.  
-  The FCC currently could not care less what hams run Provided that we 
do Not Cause Interference.  The last ham to get in trouble for running 
more than 1500w was causing interference to one of his neighbor's music 
systems.  The neighbor happened to be an FCC field inspector -- the same 
one who wrote the citation, no less.  . The moral to the story is:  It 
might not be a really great idea to run 22kW every night on 75m ssb in a 
housing tract.
