Kingdead57, sorry for the time past.
First, I'll try to response:
QUOTE
does it matter which kind of parts you would use to repair your power supply?
I don't know if I certainly understand it, but if you mean if you can pick any component with near specs, no. I don't recommend it. If you change a resistance of 1Mohm with a tolerance of 2% with one of 10% it can be bad.
Try to find a fuse with the same specs as the one in your board.
I don't understand how you deduce that it is the PSU.
And I think that there is something very strange on your pic.

What was 4 resistances, in your one, seems like them are short circuited. I supose that it's not been made by you, is it?
To be sure that is the fuse what causes the fail, get a tester. If is it, buy one with the same specs.
Good luck.
You posted more than 2 weeks ago, so I supose that you got your machine repaired anyway.
