Working with power supplies for years has exposed us to repeated scenarios of "the main transformer is shorted" or "Solenoid is burned out". Our solution was to buy a manual winding machine and stock the various guages of wire and just re-wind them as needed. If you have a transformer that needs to be replaced we'll disassemble it noting winding numbers and construction details and then we can make you one or many new ones to match. We have various cores and bobbins in stock as well as all the specialty tape and teflon sheathing required and we can Hi-Pot test the transformer to 3kV when completed.
