D4K5 Class D Power Amplifier

This is the classic D4K5 Class D audio amplifier. Based on the power sulpply the amplifier can generate up to 600-700W on 4 ohm. The bias is beetwen 8 and 18V. The supply is simetric and it can be between +/-32 to+/-90Vcc.
Attention: The bias negative lead is directly connected to negative rail so you need a galvanic isolated supply for that, DO NOT CONNECT it to the POWER GND.
