I am in need of a motor for my tower raising winch. The tower is an old Wilson RB-45A tubular tower. The power winch is a Towtec Corporation Model 102-A. The motor within the Towtec product is a 110 VDC Ambac Motor, model C-2100. Does anyone have a line on a replacement motor or any suggestions for repairing the existing one? Tnx & 73, Mark, K6FG
