    This bulb will fit in the original socket.

    The main problem was the dichroic filters and levers.
    I took the assembly apart and cleaned everything.
    The dichroic filters were in good shape and needed to be re-guled to the lever arms. I used silicone glue.

    The stacks of separating washers were different at the pivot and the sliding ends of the moving filter levers. This was rectified.

    The springs were buggered and they were straightened at the ends and put on the correct hooks, so they don't interfere with each other.

    The number counters were not making contact with the filter wheels. This was easily rectified.

    Some of numbers are rubbed off (How, unless someone kicked this thing around on the ground without that cover plate in place????)

    The back panel was straightened and re-painted in a few areas.

    Here is the finished product. Well, almost finshed. I need to do the foam light seals, but I'll wait until I get if fired up so I can test the seals as I go.

    I re-painted the numbers by hand with white enamel and a 000 brush (Hey, I do have an art degree, after all).

    OH, wait, what about the 120V conversion???

    Well, after thinking it over, I thought it best to do the conversion in a separate box, like the original power supply. This would allow the use of the original single cord that exits the lamphouse. Things are so tight in the head that extra wires could be problematic. Also, by keeping the head original (except for the bulb), it could easily be hooked up to the correct power supply if needed.

    The ideal conversion box will be a trashed power supply, as it will have the appropriate 6 pin connector. Anyone out there have one?

    Also, a 24v transformer can be had for like $10, so it might be worthwhile to just go ahead and put a transformer in my box. I'll see what kind of a box I can come up with.

    The ELC bulb is about $10 wheres the EXX bulb is $20. So, in the long run it might be actually cheaper to buy the $10 transformer and use the cheaper 24v bulb.

    Also, I took the mixing box apart and inspected it. It seemed OK, only a slight yellowing. The the diffusion plastic was quite dirty. I cleaned this well and re-assembled the box.
