[Heathkit] hook-up

[Carl]

I believe the 850 uses (not positive) SS control; I rember having to 
outboard a 12V Dip relay to control a SB-220 which has a +125VDC line. 
The SB-200 is -125VDC

HI Paul,

The issue is the 850 probably has a 12v keying circut. The SB-200 has 
probably a 150 volt line that needs to be grounded which would fry the 
850 relay   Just guessing as I don't have either radio. So you need to 
find a relay that is a 12 v one (or whatever the 850 uses for keying) 
and use the contacts on that external relay to key the SB-200. Does the 
same thing but with an additional relay. You do however need to have 
that relay in a protected case so little fingers or curious paws cannot 
touch it.

Good luck if I can answer any thhing more please feel free to ask. 
However I hope someone form the Heathkit list with an SB-200 would step 
forward and help.

Sorry no one on this list gave you a honest answer although Jim's was 
pretty cute.

  Put them all in the same room, pour a few cocktails, turns the lights 
down low and see what happens.......
