Hi all, I have a problem that has recently cropped up. When I key my 200 with my 746pro set at minimum RF power output my Grid current is sitting around 300ma which I feel is way to high! I can hear the relay clicking but my theory is that the -135v BIAS voltage is never being removed. And how would I check my theory? Does that make sense or am I barking up the wrong tree. Please any help apprciated.
