Dual Channel 2sk1058 2sj162 Mosfet Power Amp

This is a dual channel 2sk1058 / 2sj162 mosfet power amplifier, built to be used a main L+R amplifier for my system. I had the amplifier tested after construction to ensure it was within rated specs - each channel is 200W (8 ohm) / 320w (4 ohm) @ 0.003% THD. I have designed a remote turn-on circuit to integrate with my receiver. Each channel has its own power supply with soft start on the line side of toroidal transformers. Cooling is achieved by tunnel heatsink assembly and a PWM fan controller. At start-up fan speed is 30%. Small thermistors are attached to the inside of the heatsinks to monitor temperature. Inputs are electronically balanced.
