[Elecraft] Ameritron AL-811H with K2 & KPA100

[JEAN-FRANCOIS MENARD]

I bought an used linear amp Ameritron AL-811H for half of the price  
of a new one. I just want to make sure I'm right. This is the first  
linear amp like this one I have.

If I want to connect my KPA100 to an Ameriton AL-811H, what should I  
do ?

It seems that Relay control conector behind the AL-811H is keyed when  
grounded, and the K2/KPA100 is keyed when positive !?!?

Thanks for your help.
