Just got back from Radio Shack. I bought a fast
blowing 250v 2 amp
fuse
and installed on in the laserdisc player. Unfortunetly, it blows just
as fast as the .75amp fuse.

There is a chance that after sitting all that time the filter cap has
become unpolarized. Every time you turn the thing on the current surge
required to charge the cap will blow a fast blow.
What you might try is to get a variac, turn it down all the way, attach
the laserdisk, turn it on and then slowly bring the variac to the full
voltage. This will give the cap a chance to repolarize without pulling
too much current. If the fuse still blows you probably blew the input
rectifier or something else expensive...
