I don't think you need to be too concerned about the +/- 10v supply, though=
=20
there will be a slight difference in the results, a +/-9v battery supply=20
will work as another poster mentioned, all the IC's can work at that=20
voltage level, only the DAC has a maximum 5v supply  and that is fed via a=
=20
regulator.

If you would feel happier with a 10v supply then there are a couple of ways=
=20
to either make or buy one.

I'll see if i can make a couple of PS circuits to help, when I get home=20
this afternoon.
