9.8 watt basic amplifier

00:57:14

It converts from 800mV( .8 volts)  to 5.42 volts, 3 ohm load(1.8 amps, 9.8 watts)

Nice topology. Works well, just s touch of crossover. I like it.

To reduce harmonics put one more diode in serie to the one you already have. Good job keep one designing

Thankyou everyone! Lol. Wouldn't the main transistors blow out if you put another diode in?

Which of the "main" Transistors? I guess you just missed than one from the original schematics

Voltransistor

The transistors that go from the load to the positive or negative (on the right side).

I dont understand your concern? You talked about one transistor, now its about two? And why is/are it/they in dangerous to blowup?

The more diodes you put in, the more the voltage drop from the path between the bases of the main transistors and they will be more of a shortage from positive to negative, especially if you take out the diodes, they both will be "on"(100 percent of a shortage)

Remember, the diode path switches, but also it protects the main transistors, on the right, from creating a short.

the diodes are to compensate to BE diode from both transistors. this kind of well known amplifier need two diodes. otherwise your amplifier sounds like shit

True! Lol.
