Not to appear to ignorant, but it seems I have to ask before it becomes obvious to me, but, across which wires (red & yellow or red only) is this placed?
Everything I took for granted about signal path and values 30 years ago has simply vaporized since I haven't drawn on that knowledge for 20 years. The occupational hazards of the past decades - horizons, white lines, driving wheels at godless hours - have taken their toll. Time now for less driving, more recording ... sound of the wheels will drive you .......
I appreciate the help ...
