The audio amplifier is built around an inverting 741 op-amp. Extra current boost is provided using the
BC109
/ BC179 complementary transistor pair. The voltage gain of the complete audio amplifier is around 15.
The
audio output of the complete receiver is really quite good and free from distortion. I may provide some
sound
samples later. Click

to see a picture of my prototype. I used a small wooden enclosure and the
complete
tuning assembley from an old radio.
