    Have you checked the power supply for contamination? I would guess
    that several substances in the studio are conductive enough to cause
    an internal short circuit. Some might cause temporary problems and
    burn away, while a small chip of metal could open the fuse. 

    I would be interested in the make up of the power supply. Your post
    reads as though you get some use out of it, and then the fuse opens.
    It's easier to find a short circuit on a power supply that opens the
    fuse on power up. 

    If the suggestions offered don't work for you, I can walk you
    through the repair.
