it seems easy to build an internal power supply, or at least a more silent external power supply, in some schematics diagram in the d8b database forum there are the pinout diagram of the voltages required for the console, +-16V for analog stuff, +5V for digital, +12 for i don't remember what and +48V for the phantom power,and some grounds, there are already power supplies that provide those voltages, its only matter of joining them together (sorry for my bad english
)
