I just bought an Acopian power supply from a local surplus guy, it is the DB12-50:

The guy has a few more, and I can get them for people for $40.

It is a +- 12 volt linear regulated power supply with tracking outputs. 500 ma output.

The specs say it has .1% Load regulation (.012 volts) and .05% line regulation. (.006 volts). Ripple is specifed at 1 mv.

There were not a lot of them, but PM me if you're interested and I'll go pick some up.

They are used, but the one I bought is working fine. I will test them before I buy them.

Yes, actually he has an entire aisle of power supplys, piled to the ceiling. There were a couple Acopian DB5-100 power supplys very similar to the DB12-50. They are +-5 volts, 1000ma.
