A note about substituting DC power supplies for AC:

This can be hit or miss.  Some systems require AC due to components with negative voltage requirements, other systems use AC simply because the rectification circuitry is placed inside the console.  On the latter consoles, using a DC power supply will cause 1/2 of the rectifier array to do 100% of the work, leaving the other half to do nothing.  Depending on quality of design, this may or may not be a problem.  It's always best to use the recommended supply when possible.  One thing is for sure:  Don't even think about using an AC supply on a DC console unless your actually trying to destroy the console.
