Rivergate does not make their own power supplies. They are a distributor for different companies that maufacture them. Usually says the companies name on the face. My Rivergate was maufactured by Todd Engineering Sales Inc. Unfortunately they are out of business now. They were bought by aaps. You can purchase power supplies directly from them at a fairly good savings.
