[Heath] SB-200 amp on AM

[Mike]

Ray...I use my Titan 425 on AM but it has a 100% duty cycle at 1000 
watts...The SB-200 doesn't have near that much head room...You'll need 
to determine what the 100 % duty cycle power level is and then reduce it 
by about 33% for the AM carrier level.  Tune it up with CW  and then 
drive it with an AM carrier to that power level..I suggest you 
experiment carefully. You will find that more cooling will be 
required...I've done this with my Titan and the SB-220..Both worked 
pretty well...A friend tried it with his FL-2100...Not so much... He had 
to add an additional fan and decided it wasn't such a good idea.....No 
sure, but the manual may address this issue...Be careful..Proceed 
slowly.
