I have already opened this ZWC up to check the pot gears alignment. Even with the pot gears loose, not meshing, the handle rotation remains the same. This must be due to the "limiter" pins (#13?) within the handle body. So, this is why I believe the handles must be removed to allow adequate rotation and realignment. This transformer came with two 180 bricks, and has the milled aluminum brackets already installed. Do not know whether it came from factory with alum brackets installed, or if previous owner did a change-out. I have changed the plastic brackets to aluminum on an older style ZWC, with 135 bricks, and other than that, they both seem identical inside. Now, for first time, to remove A and D throttle handles to return them to proper positioning. BTW, the red mark for the handle position/voltage, has been painted on in new place to reflect the offset position of the handles. And, yes, the original red position mark in there, in proper location. Thanks to all for the input.
