[Amps] Control transformers

[Jeff Pederson]

   Good day,
    I have learned alot from this list over the years. What I propose to try may work or it wont. Im thinking it wont work but it dont hurt to ask. From time to time I come across 1kva,2kva,3kva control transformers. 0 -120v on one side and 0 -240,480,575,600 volts on the other. If I was to series two of the 600 volt windings then feed a fullwave doubler, would this work or not? I would also like to series the 120v side feed it 240v. For there intended purpose I think with control transformers, the higher voltage winding serves as the primary and the secondary is the 120v winding. Not sure how robust machine control transformers are.or if there is enough insulation between primary and secondary. Im sure current capacity would drop if I step up the voltage.
