20 years ago lightning punched a hole in the ceiling of my basement apartment and burned both ends of a curtain rod 6 feet away from my powered up keyboard setup. Only my Jupiter 4 went dead of 6 keyboards that were powered on. The Jupiter 4 was the only keyboard with keys held down when lightning struck. 3 months later my prophet 600 needed a new computer chip. I replaced the fuses in my Jupiter 4 but they instantly popped when I powered it back on.
My question is do you think this keyboard is fixable? would it just be the power supply? Any ideas would be helpful. The keyboard is stored 2000 miles from me but I could retreive it next time I'm out there.
Note: It is a modified version with 64 preset memory locations.
