Plate transformers: After using a "pole pig" for 30 years, 2600 volts in a 
voltage doubler ckt with variac, it's starting to hum a little.
these days. I am thinking about doing a rewind this winter, building a jig, 
increasing the size of wire on secondary, and decreasing the size on the 
primary for more current capacity, new paper etc, and changing to a bridge 
rectifier ckt. Can someone recommend a book on the principles and the practical 
approach to this kind of project. Maybe someone has tried this already and 
either had great success or would never do it again.  thanks, K4AVC
