Distortions will sell you a new power supply and cord. I think I paid $20 to replace one I accidentally ruined. All my Distortions stuff is packed up because we are about to move or I would look up the rating for you. The people at Distortions are easy to work with. If you call or email they would tell you whatever you want to know.
Thank you for the replies. The Twitch I bought was new but out of the box. I bought him at an auction for a Halloween store that went bankrupt. I only paid $35.00 for him with some other stuff so not having the power supply was no big deal. Came home with a truck load of stuff for just over $500.00. I know the power supply is 12 volt I need to find out the amperage.
