while adjusting the GB knob in a negative direction on the Eldorado uMax it interferes with the threshold tone causing it to raise up an down quite strongly just as if tuning a radio station , when adjusting the GB knob in a postitive direction there is no change in the threshold . The detector functions perfectly and is very easy to GB , I am just wondering if this is normal or maybe a sign that something is on the way out ? I only have the Tejon to compare and while adjusting the GB knob in either direction on the Tejon it cause's no interference to the threshold ...
