I'm trying to revive an old project which was built without its own power section/voltage divider and never was powered by anything other than a bench supply. Ideally I'm looking for something similar in spec to the now discontinued Elpac WM072-1950-D5. Any suggestions on a similar product?

Elpac makes this one which is still current:

WM063-1950-D5 Elpac Plug-In AC Adapters

I think I may have one of these and don't need it if you are interested.

But you might be better off with the low current bipolar power supply from Twisted Pear audio.

Low Current Bipolar Power Supply (LCBPS) - A Regulated CLRC Supply

I couldn't find specs on the Elpac that you linked, but the LCBPS looks interesting. How would that compare to a dual TREAD setup? Now I'm just debating if I'm up for playing with 115V AC....

tread is pure analog.

I have no idea about that brick thing. anyone know for sure?

I see those things all the time at the local surplus store

but they seemed very light, so I assumed they were switchers and not analog.

5V DC @ 860mA +/- 12V DC @ 300mA
The pinout is the same as the rest of the triple output WM series .

A dual TREAD PSU would be more comprable to the Twisted Pear Low Current Dual Power Supply.

Low Current Dual Power Supply (LCDPS) - A Dual Regulated CLRC Supply

I guess I should have inquired about the current requirements for the device you plan on powering before suggesting something.

One possible way around it was discussed some time ago in the Dynalo construction thread.

Yes there is a very good solution which is a standard unregulated wall wart that outputs AC voltage. With a couple of diodes and a couple of capacitors, you can use a little trick known as a "voltage doubler". I have done it, and it works really well. True +/- supply and AC wallwarts are easy to find.
