Flyback transformers are a great source of compact, efficient and powerful high voltage (hence why they are used in almost all CRT devices) but I figure the biggest ones would live inside CRT projectors. Where does one buy replacement Flyback transformers from?

I am using them to generate high voltage for various physics projects and currently use a number of smaller flybacks from large CRT TVs, but I'd love to get my hands on a couple of big fat flybacks, and I think a spare parts supplier would be the best option. A google search has turned up nothing useful, does anyone know where to buy big flybacks from, and even recommendations as to which projectors have the biggest flybacks in them would be much appreciated.

Thanks all!

I don't think the current output is going to change much from flyback to flyback, but I could be wrong.

www,mainelectronics.com might be one source here in Canada, otherwise eBay has a zillion of them.

And wouldn't the voltage required for a 8" or so CRT in a projector be less than that required for a big direct view CRT set?

Thank you for the advice, Ebay was a very logical and surprisingly good avenue I had not explored.

Output voltage of the secondary isn't a huge concern, as it's possible to generate enough voltage to break down the insulation on just about any potted secondary with the right customised primary. I think you're probably right about the potential difference requirement being less in a projector tube, but current handling is my greatest concern. Thanks.
