This circuit amplifies signals from 0.5 Hz to 300 kHz. We found it in an old documentation. Equivalent transistors may be used. The gain is 20 dB.
This simple MW radio was found in a 1975 publication, but it can be mounted with BC548...
This circuit is basically the same as the previous configuration (CB15616E) with a power stage with...
