I have long wanted to build an audio amp for my regenerative receiver, so designed a simple one-stage affair around a BC547 transistor.
I used what I had in my junk box to build the amp.
I hooked up my Hantek 6022BE oscilloscope and wasn’t impressed withe the output signal; it was cropping off the top of the amplified sine wave.
I tried changing the values of the biasing resisters until I finally achieved a better result.
Now it was time to integrate the amplifier into the receiver and turn on the power.
The result was pleasing. It worked. But the sound isn’t exactly room filling. That hopefully will change when I build a second stage just the same as the first and add it to the system.
