AF Bech Amp
Small
and self contained.
I
have been wanting to build one of these for a while. I already had
two audio amps on the work bench, but I wanted something that was
self contained, and did not have to have wires running all over.
This little amp is based on the LM386, has a small speaker built
into the box, and an RCA plug on the end. A probe type attachment
can be added and it makes a great tool for troubleshooting audio
sections in radios. The little speaker built in the box is not the
best sounding, but it lets you hear the signal, which was the goal
with this little amp. I also included a 3.5mm jack on the side just
in case I wanted to use a better quality speaker.
Schematic of my bench amp. Nothing secret here!
