DIY Metal Halide ballast upgrade?
 

Hi all,
I have a broken magnetic 175W MH ballast (dual) laying around.
AFAIK it works, but I'm wondering if it's possible to find proper
capacitor and turn it into 250W. There is a bunch of outputs on the
transformer marked 150W, 175W and so on up to I think 800W.

Does anybody know a sourse for schematic for this stuff?

What do you guys think?

Thank you
Yuriy
