Wiring a transformer for practical use?

[Blair]

I have a 1kv transformer that has two 6.3V taps.

I'm not sure what to do with it, and then after a few cold beverages, it hit me that since it was wired for 115 and 230V mains that I could just shift my wall supply from the 115v tap to the 230 and it would essentially make me a 500VCT with two 3.15V windings where I could use the wires where I series them as a center tap.

Can I do this without any damage to the transformer?

Any source frequency issues, or is 60Hz ok into the 230V line?

Does it make sense at all is a better question;))

Thank you!

Yep, you can. It should still have the same VA rating, but limited by wire size. Theoretically if it is a 1000V at 100ma then with half the primary voltage it would be 500V at 200ma. Someone else will know better.

You can use two 3.15 filaments to make 6.3, just have to keep the phases right. You'll get either 6.3 or 0. At 0 you'll be shorting them.
