From the : 
"2-11. A single source of +20 to +30V dc with 10% regulation may be used to power both the oven and
oscillator amplifier circuits if a simple IC regulator is used. A suggested circuit is shown in Figure
2-1. The resistor and capacitor connected to terminals 3 and 4 of the IC minimize ripple and noise
in the regulated output."

I have planed to separate the power supplies from my test stands as my next project for the 10811's so I'm also interested in a suitable supply.  Considered a battery supply with a regulator for the 12 V side.
