Digi 002 rack power supply

[tromnek]

Hi.
I recently found a broken Digi 002 rack thrown out on the street.
It appears that the power supply has failed. I tested it and it gets 122 volts to the input rails, but nothing comes out of the output rails, the fuse on the psu shows continuity so there must be a failure somewhere else on the psu (Skynet, DGN-8U50).

I don't have a use for this equipment, however my friend's 16 year old son is currently recording his band and is interested in this unit if I can fix it.
It would be a great piece of equipment for a young kid to learn with.

DigiDesign wants $125 for a new power supply. But before I get a new psu I would like to test it with a PC power supply to make sure that it will work.
However, I don't know what voltages correspond to the output rails.

Does anyone know this information so I can test this unit. The wires on the output psu harness have the following colors.
Yellow
White
Black
Black
Red
Red
Blue
The sticker on the back of the psu documents outputs of +5, +12, -12, +3.3 dc volts
But which voltages corespond to which wires on the output harness?

tia,

welcome

make sure the contacts are clean and seated well

you would be better served asking up in the LE area

this is the bone yard area: 001, mBox 1, Mix hardware, Expansion HD hardware, AM3 cards, Sample Cell,

Hi there did you fix the PSU?
I m experimenting with linear psu for both analoque & digital board.

Hi This is pathetic to reply to a 3 year old thread but Tromnek, have you find out by the way which colors correspond to which voltages etc? I have the exact same issue with dead digi002 power supply
