[sdiy] Really Small Linear Power Supplies ?

[Ken Elhardt]

I've extracted the 3 Band Resonator section from my Polymoog synth,
and the parts are spread out on my desk hooked up to power and audio,
and it's working great as a separate unit.  It needs to be put in a
case, and all I need is a small dual output +/- 15 volt power supply
that only needs to power about 9 opamps and a 4016.  I've looked
through Mouser and Digitek catalogs, and so far I can't find anything
smaller than a Condor dual supply at 4.88"x4"x1.68".  While that may
sound small, it actually is quite large for this project.  The width
and height of the case is determined the by part of the front panel I
hack sawed out of the Polymoog.  It's too large to sit vertically
because of my 2.5" height constraint, too big to sit on the side of
the PCB, so it can only behind the PCB.  This is going to make the
case at least 16" deep, which is huge for what should be a small piece
of gear.  When I look inside some single space rack gear, they have
small transformers and a few power supply components on the part of
the processor PCB which overall, seem to be much smaller than what I
can buy.  Does anybody know it's possible to buy something really
small like those in rack gear, and if so, where?  Thanks.
