You should probably post this in the solid state or even chip amp forum. While you can make a Pass clone amp at 200 watts, you are talking about Class A heat, heatsink requirements, and power supply.

Pass does have the X series of amps that are class AB, but are not simple to build. Uli made a board layout you can download in the post "normal x-amp", it's 200 watts, but requires balanced input for best performance.

You may be better served with a standard class AB discrete amp, a class B chip amp, or even a class D amp for much higher efficency.
