66Vx10A=660W, and your amplifier will be 75W/4ohm with +/-33V rail voltage, 150W for both channels, with 70% eficiency of AB class you need 200W from PSU minimum, I recomended 300W, but 10A rectifier will be OK. Regards |

AX14 also can work on +/-33V DC with same performanse and 75W/4R output power, I recomended TDA7294 just for begginers.

thank you.
by the way, do you have one pair output amplifier design with opamp at the input? do those amps sound good or is it better to have discrete components at the input instead of opamps? |
