MSB Link DAC from the 90’s - Help!

[Imago]

Well, I stumbled across this the other day and thought I’d make a little stereo system for a friend with a disability.

Trouble is, I can ‘t find the power supply which is likely a big wall wart, or I never had one to begin with.

What are the odds of someone having one, or helping me build one? Looks like a 6 pin DIN.

I hate to throw things out…

From memory, it needs a P1000 Power Supply... but there's also a wall-wart option if I'm not mistaken. Try MSB

Called MSB and no dice, they said it's too old. Anyone have a wall wart kicking around so I can try it out?

Alternatively, would it be hard to make a power supply? I think it has 2 voltages...

Have you Googled? Google and you shall find.... within less than a minute..... the power supply unit PCB with voltage rails values clearly labelled on the PCB. Then remove the DAC unit lid and figure out which rail goes where. It is an 80's unit.... check what kind of rails those DAC current-out R-2R chips from 80's required.

Yup. Lots of room under there!

+ 20V will go to that 18V reg.... the rest you'll figure out by looking at the electrolyte orientation with regard to PCB common (PCB ground)

Show us the rest...

What would you like to see?

I did own one decades ago. It’s just a simple transformer with diode and capacitor with the above dc values.

U have to rediscover the pins for the right power values, trace the pins to the regulators to determine the analog side, and the digital side (probably +-5 ). Big pin tab is common ground.

Is this for sale? Or want to make me one?

 

[angchuck]

$500. I will give it a go or else it’s a diy forum not Craig’s list

Okey dokey. I'll make my own.
