Powerstat Variable Autotransformer

Powerstat Variable Autotransformer.  Don't know much about these.  It has a GE Transformer hooked inline with it along with output receptacles.  Excellent condition.  Will probably need to ship on a small pallet because it weighs about 150 pounds all hooked together or could be disassembled and shipped in separate boxes.  Selling AS-IS.  Came from a transformer manufacturing facility.  I will be more than happy to assist in getting unit shipped properly.
