Hello All, Here I have gotten the modulation transformer for the Tucker KW out, and have had a look at it.
It seems to have windings separated by thick layers of some kind of black (tar? -but not soft) impregnated paper. The outside has what seems to be windings of cloth tape around it. In one place on the bottom, the insulation has been damaged or torn enough to expose one lead-in wire, which seems to be intact. I have no problem dealing with this, and insulating the area, patching up the outer covering, but here's my question: How to hi-pot?, Any dangers in such a test? Should I try to drive any moisture out of the transformer? It has been in a household garage for 8 years. Any advice what to do to take care of this part would be greatly appreciated. I doubt I would find another one so large. It was mounted with the frame ungrounded on a wood board. Should I re-mount it ungrounded like that? And yes it is extremely heavy! Can anyone identify it? No numbers/markings except the frame says "BETHLEHEM", and the terminals are simply marked P, B+, etc.. Here are pictures; http://208.190.133.201/tuckerkw/modxfrtkw.html
