Mark Levinson ML-1 power supply


I recently purchased some vintage audio gear at an estate sale auction. One piece of gear was a Mark Levinson ML-1 solid state preamp, which dates from approximately '77 to '80. Unfortunately, the external power supply was not included. Thus far, I've been unable to find a replacement online. I'm hoping something eventually pops up on eBay. In the meantime, I'm thinking of building a quality power supply so that I can actually make use of the preamp until I find the real deal online.

I have experience with a soldering iron building speakers and can follow (though not design) a schematic. I've never dealt with power supplies before and don't know the first thing about them. Mark Levinson tells me that the power supply was plus or minus 15V, 500mA each rail. They weren't sure of the pin configuration, and the connector is a bit of a mystery as well.

Any suggestions or insights on where to start would be greatly appreciated. Thank you very much.

The Calex AC/DC supplies require simply soldering a fused AC power cord to one end, and soldering DC application to pin connections at the other. They are potted units that would ideally be repackaged in a DIY enclosure with umbilical to ML. Talk to one of their techs by phone if you want the straight story.

Allied Electronics, Burson audio, and others have similar PCB solutions for use in DIY enclosures; Calex has a particularly clean spec.
Its really sad all the bad press ML gets on this site. I had great luck with their customer service about 2 yrs ago and they were very helpful. Is there something I am missing here lately?
Hi again everyone. I eventually did find a PLS-151 power supply on eBay, but without the cable that goes between the power supply and the preamp. So my search has continued. I have been totally unable to locate replacement connectors to have a new cable created.

But then this popped up on eBay: http://www.ebay.com/itm/320809490701?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_528wt_1139

Is this what I need? Or is this the cable that goes from the power supply to the wall? The seller hasn't responded to my inquiries, and I don't want to let this slip by if it's the right one. Any tips are greatly appreciated. Thanks!
Assuming that the description is accurate, "DC CABLE for Mark Levinson PLS-151 Preamplifier Power Supply," that is what you want. It wouldn't say "DC" if it was referring to the power cord to the wall.

It's taken a lot of patience, but it sounds like you're just about there! Enjoy.
