Studio Color 575 Won't Strike

I've got 6 1997 Studio Colors 575 I got used. Lamp hours say 7000 something and lamp strikes say 3000 something. The total fixture hours are OVER. They've been sitting unused but powered on for probably years. Cleaned them up and I'm ready to go, except...

On all of them either F1 or F2 on the lamp board is blown. Now, HES says it's a 16A Fast or Ultra Fast blow...depenping on where on the site you read. But the board says 16A slow. Since I couldn't find either, I went with a 15A Fast. Figured it was safe enough and they must be some wiggle room right? Anyway, I mostly wanted to see the darned thing work. Replace the cover, turn it on and nothing. Look inside again and the new 15A fuse is fried. Somehow I'd let all the smoke out. Replace with another 15A but leave the cover off this time. Hit the power and the fuse lit up like a strobe lamp. It was a very short show but as least I had light, right? :18: Oh wait, it's supposed to be light on the outside.

Based on what I think I might be looking at (I'm hardly an electronics guy) it looks like power comes from the wall through the switch then through the RFI filter and straight on to the board. Looks to me like the filter could be bad but what else? And what do I do next?

Any help would be huge. And I gave the history in part to help troubleshoot and in part to solicit comments on what other damage I might still be looking at. By the way the Vers is 39E, it's a 575S plugged into a 120v/60Hz circuit, and the boards look mightly clean...no burns, exploded capacitors or dust.

    As for the crimps, you are correct, there is very little slack, you will probably be better off just leaving them without the covers, as long as the crimp is still good, I would stick with that...
    as for cleanup, I would just clean the crud off everything as best you can, it should all be fine...

    As for your other studio color, I would replace the Lamp power supply with one from another unit, it sounds like that is your problem there,
    unless the wire from the logic card isn't plugged in...
    there is a gray wire that runs from the logic card all the way across the fixture to the LPS, it is the only connector plugged into the LPS that has more than 3 pins... off the top of my head I believe it is a 6 pin connector, but I may be making that up, I am pretty sure that all the pins are not connected however...

    As for a manual, not so much, there is a training class in austin that many of us have taken....

    Good Luck!
