Simple Current Feedback Power Amplifier


Posted on May 20, 2012

Figure 1 shows the circuit. A major change from all of the designs from that era is the speaker coupling capacitor - 1000uF (for a -3dB of 20Hz and a 8 Ohm load) was the most common value. This is too small, and the 2200uF shown is actually marginal. 4700uF would be better, or even more - but that would defeat the purpose, since the amp would no longer be cheap.
