I had one.  They seem to be making modifications all the time, so 
current units may not be the same.  I had a certain amount of trouble 
with mine, however Henry was reasonable about fixing it in the warranty 
period.  Later I had a problem with a nasty oscillation when the amp was 
used on 15 meters, which blew one of the transistors.  I replaced them 
all with a matched set of 8 from RF Parts.  You will notice that output 
drops off significantly on the higher bands.  I never got more than 
about 500w CW on 10 meters, although it could easily produce more than 1 
KW on 160 and 80 meters.

Yes, 8.
