Seems like this has been discussed a few times, but ....

The SB-220 is capable of far more than that -- 1 KW input was the *legal* 
limit in those days.  Driven with 100-110 watts, an SB-220 will/should make 
at least 900-1000 real watts output on CW when run in the SSB (high 
voltage) position, and will do that year after year.  NMine measures about 
850 watts out on 12 and 17 meters, so even allowing for measurement 
tolerances, Bert's doesn't sound up to snuff.  I wrote him off-reflector 
asking what the input SWR and driving power indications are, thinking that 
maybe his transceiver is rolling back its output.
