When the pan servo stalled it burned out (don't ask). On taking it apart, there is a small printed circuit board in the lower part of the servo (where the wires enter the servo). There are 1/4" wide IC's on there and a small piece of insulating paper -- I suspect (because of a small scorch mark) that the left-hand of the two IC's (with the servo upside down and the drive gear at the top) has burned out. Tabb: Is it possible to get a replacement for this PCB? The motor and the gears appear to be in great condition. I think the IC acted as a protective fuse. Thanks Andy.
