Chapter 5: Upping the power

There are requests for this board to be used with higher rails. In the order of +/-100vdc, or 500 watts RMS into 8 ohms. Stuart Easson is working on the prototype. He has designed a CCS for the input differential allowing the
amplifier to be run from 20 to 120 volts. He has so far successfully tested the prototype into 4 ohms but needs a larger power supply.:

Also if you need more power there is the KSA-100 clone project, whose wiki can be found [here]
