Go to Home Depot and get a "cheater plug". Try to get one that has 2 spades, and no ground (long, round) connection. If they only have the grounded type, just cut off that round pin. Plug your cheater into the wall with the amp attached. If that doesn’t do it, try unplugging the cheater with your amp connected and reinserting it into the wall upside down. Post your results. May the force be with you.
