摩托罗拉高保真功率放大器电路 (Motorola Hi-Fi power amplifier)

This is a very simple, low cost, Hi-Fi quality power amplifier. You can build it 5 ways, like its shown in the table (from 20 W to 80 W RMS).

Some comments:
- The first thing that you must do, is to measure the end transistors (T3 and T4) amplifying coefficient, the hfe or β. If their disagreement is bigger than 30 %, the amplifier would not give a clear sound. I used MJ3001 and MJ2501 transistors, and this disagreement was around 5%.
- Before the first turning border=0>

I am very contented with this amplifier. It gives a very good sound quality.
Have fun with it!
