As described in another thread, I have a MK IV that has blown two power transformers, each time after over a week of heavy use. It has been suggested that perhaps the output transformer (old/original?) has an intermittent internal short. The leads on the output transformer are old, brittle and flakey and so I removed the bells expecting to find lugs where I could solder new leads. Well, it ain't so - the ends of the old leads are behind some kind of paper wrapping. Before I operate on this wrapping I thought I would ask here if anyone has any tips or info about the best way to replace the leads? It now seems to me that it may be better to simply splice as close to the transformer as possible where the leads seem in decent condition? I also think that it might be a good idea to add some kind of fuse(s) inline with the output transformer that would blow if there was a problem, and so save the pt?
