Hey guys,

Not sure if there's much love left for these, but I recently acquired 2 of them - a 24 chn and a 32 chn.  I know the power supplies are getting tired in these, and the automation supply is required to drive the buss outs.  I've been told that many parts for the PSU are now long obsolete, so I'm wondering  what my best option is with these.

Any thoughts much appreciated!
Thanks,
Sig

Is there something special that a PSU from international power or lambda could not resolve?

Well, you know that's been my thought.  I've always been told that it was such a big deal that these power supplies weren't gonna last forever, but I'm certain that a replacement could do the job.

I don't really understand why there's a separate automation computer PSU to drive the buss outs either...it was the ARMS 2 Diskmix system that was on this thing, circa 1986/1987.

Do you have any schematics,  hookup info, or computer program for the diskmix?

Well now is that because it has disk mix on it and that the non automated mix boards do not do that?

I have all of that in storage, it's coming back here in the next week.

The automation PSU apparently has to be on, but the diskmix computer (a 286), doesn't.
