[Elecraft] Anyone using a Heathkit SB-200 with K2/100

[Eric Swartz WA6HHQ - Elecraft]

Lee - The KPA100 can easily key 130 Volts as long as it is a -positive- DC 
voltage. We put a high voltage keying transistor in the KPA100 just for this 
purpose. Our keying line spec is 200V max at 1A.

Sam may have a problem with the SB-200 though as I think it has a negative 
keying voltage. If it does, a relay will need to be added between the K2 and 
the amp to key it.
