That's a really lucky ebay find!Oh crap, seriously? I can find a similar one and post it. It looks old with wires coming out of it. It has a sticker on the side saying not to use in construction because it doesn't have a GFI.
I'd have to say it looks just like this one, but is 9kv instead of 5kv.Gas Tube Sign Transformer 120 Volts Actown FG 4047 | eBay
Edit: Oh, now I know what your saying. No it is the iron core type not the ballast type. It costs a lot for shipping too, so it must be heavy.
And it is 60htz out I'm pretty sure.
Also, I think I know why yours is only 3ma. It's because the smps ones are designed to work with different tubes. They self determine how much current is needed and output that much. Also, they're high frequency. Imo, they're like a higher voltage electronic ballast.
For the smps, yes, the load determine the draw. I think tha it is the resistance(or impedance if you don't rectify it) of the plasma that determines the current. I had one on hand from an old neon sign. I used it to power a discharge tube with 22 ma optimal but got only 3 out of it. Oh well.
For the iron core ones, I thought that the load also determines the draw on these? Although my limited experience is only with microwave oven transformers.
