Audio
Gainclones are a DIY version of a $3000 audio system called the GainCard.
NGALAC possesses a LM3886TF based dual supply amp which requires a split rail +28/-28 DC supply
Example DIY circuits which are easy to build with clear instructions
DIY PSU price is very high, will compare to purchase options
Using computer PSU may be possible after boosting +/-12 to +/-28, however, current on -12V line may not be enough to rate maximum wattage
