Michael,

I know a lot of contesters and none of them have ever gotten the SB220 to do 
more than 1200 to 1400 out and that was with a rebuilt power supply.  The 
Henry 2k4 will do 2 KW out for a whole weekend of contesting but, of course, 
that are a lot bigger amps made than an older amp like that.  The SB220 I 
had ran 1200 key down output on CW but it, too, had a rebuilt, heavy duty, 
power supply.

Phil.
