I am having trouble with biasing of the driver and final. I can’t turn driver down below about 75 ma.and then it drifts about to about 95 ma when keyed . And I can get the final down to about 75-80 at the lowest but then as I hold down the key, it will slowly drift higher to well over 100 before I unkey. And there is no RF output at all despite that. Voltages appear normal at the driver and final. What the heck!! Help! Why do they both drift higher?
