My team and I are in the process of building a plasma speaker for a EE capstone project. We've already built a circuit and gotten the thing working, and we are currently in the refinement stage. Our first goal is to get it off of lab power supplies and use rectified mains, but I am also interested in finding a good standardized Flyback to use that will deliver consistent performance without a lot of guesswork. The reason for this is that we are all interested in taking an example home, some of us even want stereo pairs.
After looking around the internet for a long time, I was only able to find a single Flyback with published specs. It's definitely on the pricy side, but if it delivers good performance and we have enough people interested to get the first price break, it will probably be worth it. I've already purchased one, and I'm going to test it out with a bench supply tomorrow, and hopefully we can retire our CRT flyback.

The one I have right now is the FLYPVM500.
Getting to the point this flyback seems to be built for this application, and is really quite a nice device, but I'm wondering what sorts of issues I might run into given the differences between it and a fly-back pulled out of a CRT. I don't know of any, but then I don't know a whole lot about transformers in general. Right now we're just switching a FET in series with the transformer, and the secondary has no connection to ground.
I'd like to know more about the design and construction of Fly-back transformers, but that sort of info is hard to come by.
Thanks!
