If you just need +12v, -12v, and +5v with a bit of current, desktop PC power supplies are very cheap.  They aren't variable and don't have the tightest regulation or lowest noise output because they're switching power supplies. But they are *cheap* and compact for the power rating.  (Sometimes for free if you ask nicely at a local computer repair place.)<br>

Subject: Re: [sdiy] Variable power supply<br>
<br>
My first power supply was made even without PCB, just by soldering<br>
components together, put inside old radio case. It was good enough to<br>
design and build DIY polysynth...<br>
<br>
Later I made uP-controlled dual supply for university project, that one<br>
works still very good after 20 years and doesn't even need recalibration.<br>
<br>
Couple of years ago I bought Tek supply (PWS4000 series), only because I<br>
needed 0.1mA readout resolution, and I dream about Rohde&Shwarz tripple<br>
supply for $1k that according to specs does all I need from little<br>
benchtop supply.<br>
<br>
What I'm saying, you can go with 10EUR DIY supply at first and make a<br>
lot of great work with it, then replace with something more fancy when<br>
you feel Gear Acquisition Syndrome.<br>
<br>
Try thi - in Polish only, but I bet you can find something similar in<br>
any electronic DIY store:<br>

<br>
Some folks are very happy with Rigol supplies, they really look good in<br>
the spect, and cost a lot less than anything that range.<br>

Do you really need it to be variable? I would think +/-15VDC or<br>
+/-12VDC would be sufficient 95% of the time. I bought a power<br>
transformer from Digikey, an IEC power inlet with switch and<br>
fuse, a Bud box, and this +/-15VDC regulator board on Amazon.<br>

If you need it to be adjustable a pair of these might do.<br>
