As others have suggested to paraphrase:  "When all else fails then read the 
manual"

The SB200 was designed in the days of vacuum tube exciters & transceivers. 
The INPUT VSWR criteria was not particulary stringent and some kit builders 
did not get too fussy about aligning the coils. This could cause power 
foldback with some SS transceivers or require you use a tuner in order to 
drive the amp to full power.
