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.

I seems to me that Levinson should be able to provide a little more help.
To me, just another example of what used to be a good company that
is now a terrible company. No support or help with older products,
capacitor problems and no help, etc. Why anyone would buy their
products new or used, amazes me. It seems that at some point you may get stuck with gear
that can't be fixed. I have owned many Levinson products but no more.
Don't mean to insult Levinson owners, but the facts speak for themselves.
Too bad, it used to be a great company.
In response to your question, any good tech could build you a power
supply. Try John Hillig of musical concepts. He can do it. It would depend
if he wants to get involved. Sorry for some of my rants, but with the prices we pay, no one want to get stuck with a multi thousand dollar boat anchor.
If I am out of line, I apologize.
