"...I have a LK-500 "B" model and it is running OK.  It has no protection 
circuits in it that I can find other than a fuse.  I cannot tell what is 
difference is between the "A" and "B" versions.  I have the original manual 
and it seems to be a mish mash of both A and B information. Do you know?"

ZA = no QSK (open frame relay)

ZB = built-in QSK using vac relay
