I’ve got my seq4 running on a wall power supply today. I built an aout_ng board and would like to integrate it with the core32. My understanding is that I need to change the power supply to one that supports three voltages: +5V, +12V, and -12V. I’m looking for recommendations for a power supply which will meet the requirements. I’m based in the US. Here’s one I found on Jameco:

Would this one work?
This is a switching PSU with 5A for 5V supply (far too much), and 2.5 A for +12V (far too much as well)
In addition, switching PSUs are not good for analog stuff.
Unfortunately I can’t give you an alternative proposal for the US (in germany we would order at “Pollin” where matching PSUs are mostly available for 5..10 EUR), but I can give you some specs:
1A for the 5V supply, only if a BLM16x16+X should be connected maybe 2A would be better.
ca. 100 mA for the +/- 12V supply
Best Regards, Thorsten.
tested and approved in Seq V4

perfect specs!
But: Epuisé :-/

yes i know. I can’t find back its box, but the brand is ELGA.
parisian people can maybe find some in Selectronic Nation, in their backstock (maybe 2 or 3 units left)
a good trick is to cut the power plug with a dremel in order to access the 220V wires. then you fix it in the rack enclosure with screws in the 4 corners. It is molded and a pain in the ass to open
I found a similar version of this power supply in the US – Elpac WM113. Unfortunately it is no longer produced and doesn’t seem to be available anywhere. I spent four hours searching for a suitable power supply. Unfortunately almost everything with those specs is a switching PSU which TK noted isn’t good for analog.
I did find a couple power supplies which look like they might work. I don’t think these are switching power supplies.

This one is twice as expensive:

according to pic : switch PSU

linear psu, so the price

the best is to make your own in this case. recycling the transformer of an old VTR is a good option, maybe using the existing circuits.

Check out this kit. It seems like it might work. It looks a little big but the price is relatively cheap:

Are you sure? it says it’s Skill Level 2.

Yeah, I use that elpac for my MBCV. Works great, hard to find though 
Hey Thorsen,
Could you give a link to a working PSU at Pollin for us lucky Europeans ? 
Thanks!
