Akai S1000 / S1100 samplers

Well it ued to power on and produce t4est tones I could  jsut never
format a disk or upate the OS. This new issue of it not havin gany power
going to the  main board makes me think its the power supply. I am in
contact with another user who has 2 S1100s for parts but shipping from
japan is gonna cost me mucho us greenback. Maybe its just a bad
capacitor (fingers crossed) my multimeter recently died on me so I need
to source another one to track down the problem.
