The simplest amp one could make though still very hi-fi. The only problem is the inefficiency and the fact that one must use enormous heatsinks to absorb the huge power dissipation from the transistors. (roughly 1/2 from the amplified usefull signal). It turned out to be a weird amp :D 110W drawn for 28W in 8ohms and 16W in 4ohms. The load on the left is 4ohms and the load on the right is 8ohms.
