Thanks Ian,

I may stick to just building dc distribution at node 0 for now, as this
is
where I have most of the dc gadgets at the moment.
I did see somewhere, can't find them at the moment, some pc blanking
plates
with 4(?) dc outlets which you could switch the voltage on and they
draw
power from the pc psu. I think a couple of these may solve my node 0
power
problem (currently have a 6 gang outlet, plugged into another 6 gang
outlet
to get enough sockets at node 0), though I'll probably need to fit a
better
psu.

The one thing I cannot seem to find is a 10v regulated wallwart supply
for
my wavefinder. But I guess I could use a 12v supply and use a
regulator(?)
to draw down to 10v?

Thanks again,
Tony T
