Look in the K3 FAQs - if you were to print it out, it is on page 27 of 34 - it is the last item prior to the heading "other". http://www.elecraft.com/K3/K3FAQ.htm (search for 6 amps) "What is the voltage and current limit to control TX amp relays? The keying device is rated at 200 volts, 6 amps." 73, de Jim KG0KP ----- Original Message ----- From: "Stephen W.
