Wiardgroup

Hello!  I have a question about the power supply for my Wiard &
sort-of related synthesizer.

The entire instrument is powered by a Cynthia "major power supply"
which is this massive lump whch can supposedly power 3A, I'm sure it
was 5A when I bought it, but cyndustries website says 3A.

Everything appears to work OK, as in, the oscillators track fine and
have stable tuning, BUT, I am getting a lot of problems with crosstalk
between modules.  The Wogglebug bleeds into nearly everything,
including the audio out of an E-Mu sampler I have on the same power
bar.  I recently built a Jurgen Haible "living VCO" module - which is
great!

but, there is a very faint vibrato audible from all of the other
oscillators, and the envelator, if it's switched to cycle mode.

This all sounds rather similar to reported power supply issues from
other modular synthesizer users.  I have the power arranged as
follows:

the incoming power goes to a splitter box in the lower cabinet, then
to a box in the upper one.  there are a pair of distributor boards in
the bottom cab, and a single one in the top, which come from the
boxes.

I seem to remember some post from GR in the archive of this group
suggesting using more than one power supply for different types of
module, but I can't find it - yahoo's search isn't very good I don't
think.

does anyone have any suggestions as to how I might power up this
monster to eliminate or reduce these hassles?

Many thanks.
