Analogue systems

All together I'm running four supplies.  I made a chassis which holds two
Condors, one set for 12 volt, one for 15, which powers most of the modules
in the large cabinet.  Each supply is good for about 1.5 amps.

The right side of the top wing, which I call the expansion unit, from the A
RS-60 on is powered by a separate Power One, an old Serge power supply
actually.  I did this because the RS290 was pulling way to much current and
making some awfully odd things happen - massive distortion in the delay,
unstable sequencer outputs, etc.  In short, the two Condors were starting to
crap out.

The forth supply, a Doepfer, is housed in its own little chassis box which
also holds my RS300 by itself.  I made my own 5 volt regulator boardlette
which worked out great.  I use a standard A Sys dual power cable (daisy
chains two connections).  This cable comes off the main supply where it gets
+/- 12 and ground and slaps them in the right palces onthe DIP cable.  It
first socket on that cable goes into my little card into an 16 pin IC
socket, and that card takes the +12 and regulates it to +5 and places THAT
in the proper locations for the A Sys power buss.  The last DIP connector on
the cable then plugs into the RS300 where it's now getting +/-12, +5 and
ground.

The RS300 pulls between 190 and about 350 mA, the Doepfer supply is good for
about 500, I'm covered, it works great.

A word about the large system - it's not as huge as it looks.  It only 28
inches wide by about 25 tall.  It just looks huge because of the lens on the
digital camera.  There is a lot sutffed in there, however as a lot of the
faceplates I had made so I could easily adapt Blacet, MOTM, Oakley, Doepfer.
Buchla, Wiard, Analogue Solutions, Analogue Systems and a ton of homebrew
gear into the same format or three RU high.  If you notice, the Blacet
module faceplate are a lot less wide as his stock ones.

The are a lot of changes in the system since the last photos were taken. the
expansion module now holds the RS290 and 295, and the two blank panels and
Doepfer A-192 are gone. The top row of the main cabinet is a lot different.
My programmable pulser has been pulled, the Moog Filter is gone (the PCBA
didn't fit in the cabinet ever and was never installed) , the outputs for
the MAQ 16/3 are gone, I have a new processor I designed in there, an
expanded boolean fucntion generator and an RS210 in which I've added
separate non attenuated outs for each filter.

And there are more planned as I am making room a Doepfer Source of
Uncertainty as it is released and I'm replacing the Blacet Final FIlter with
a Buchla Bandpass clone I've slapped together from Mark Verbos' art.

The A. Solution unity gain mixer may have to go forever to make room for
this stuff.  Although I hate doing this as mixers are always handy,  I
hardly ever use it.

Sorry for such a long posting.

best,

Peter
