Vintage Synth Repair

Hello,
  Instead of tracking down a 1980's electronic part for a power supply, consider just using an inexpensive surplus PC power supply.  For $5 I got a used Dell 250Watt supply that has no trouble putting out 3A at +5V along with several amps at +12V, -12V, and +3.3V.  I believe that you can add the voltages together (for example: Gnd -> +5V +++ Gnd > +3.3V ==> +8.3 volts) because each branch output of the power supply is isolated from the other branches.
  An old PC power supply is a cheap way to get a high current regulated power supply if you only need +5V, +12V, -12V.  Most newer supplies have high current regulated (>5Amps) of 3.3V along with -5V.  Usually they require a minimum load on the +5Volts of about 1/2 amp, but the surplus Dell supply that I bought doesn't need a minimum load.
