Ah yes. Should have thought of that...
Would the 3031 cope with supplying the 250mA @ 5v, missing out the P3
regulator ?

There's only +/-12V on the 3031 board. The tbDAC does generate +5V
though, but only up to 100mA. However, you could drive the P3's 7805
from the +12V output of the 3031. But again, you need to watch the heat
coming off the regulator on the 3031.

Maybe a 20R resistor in line would be a good idea to keep the noise and
the heat down from the P3 too.
