 ```Something ingeniously simple like this is what we need. I just tried 10 volts into my Audio Buddy and the main power LED doesn't light. I recall discussion about Len Moskowitz's involved M-Audio Duo modification for portable DC which also has the 10 VAC input.=A0 The phantom power LED will light with a 10 VDC input; this might be a clue as to getting more power to this part of the circuit. We were attaching the 4- 9volt batteries for +18 and -18 before the regulators. The phantom voltage provided was low, ~40 volts. The A-B spec sheets shows the 10VAC at 300ma; the 9 volt batteries don't seem seem have have enough current. If someone on this list familiar with this kind of circuitry has the interest and time to work out a portable power solution, I'll send them my Audio Buddy to study and modify.
