Query: Pana-Vue Slide Viewer

We ordered a used Pana-Vue Slide Viewer, through Amazon, assuming that it would be in "good" condition. It arrived in a box that appeared to have been setting on a dusty shelf for the past 25 years. That was not the problem, however. When we installed new batteries, the whole viewer got very hot. We removed the batteries, checked the installation instructions, checked to make sure we had the correct batteries, and tried turning on the viewer again. The same thing happened - it got very hot and we were concerned that it would blow up. Since we had lost all the packing instructions, we ended up throwing away the viewer. We are not happy with this order!
