Try to build this in real life and tell me if it works. And good luck! The amp will stay in class A mode until the input voltage goes above 750mv in 8ohm load. The amplifier's idle current shoud be around 1.5Amps per rail. And be careful and use big powerful output transistors (150W TO-264,TO-3pl,TO-3 package). And the class A driver with the 15pf capacitor will need a heatsink. On the power supply of things use 2x 10 000uf capacitors each per rail and put small ceramic caps in parallel with every diode on the rectifier and in parallel with the 10mf caps. Btw im 15 and on 24 jan i'm turning 16 wish me luck cuz for my bday i'm going to buld this. And if this design doesn't work try building Rod Elliott's P3A and bias it into class A i tried but it didn't work. You are the judge with or without a half current mirror.
