I think the arc on the MH is too big. As it is a DLP, you will have to get the maximum light into the light tunnel. The best way would be to find where the arc position would be originally if the original lamp was installed. Then use a lens to converge the light to that point.

Don't trash it. It's a lovely projector. I think you should try the guys at LumenArc. I enquired about a ballast and they seem to stock a few for different projectors or they may be able to source one for you. BTW, how do youknw that the bulb and ballast both are faulty. Could it not be one but not the other?
