Pana-Vue Transformer/AC Adapter

Product worked perfectly with a Panavue slide viewer I have had for probably 40 years. I never had an AC adapter for it, we always used it with batteries. Slides were so much cheaper than film developing back then, so my family's early years are on hundreds of slides. I recently decided to revisit the slides we took so many years ago and could not get it to work with even new batteries so I decided to check Amazon for another viewer. When I realized there were still some of these viewers out there and they weren't cheap, I found this AC adapter. It appears to be good quality and the viewer is brighter than I remember it being on battery power. I will be able to sort my slides easily.
