 Te> I've been using two 4500VAC 400ma plate transformers pulled from copy 
 Te> machines. These transformers (GE) have an extra winding that is 
 Te> connected to a 660VAC 10uf capacitor.

 Te> Questions: What is the purpose of this capacitor? Power factor 
 Te> correction? Current limiting? What effect would result by changing or 
 Te> removing the capacitor?
