This 80's circuit uses a germanium transistor like the AC121. The circuit has an output transformer of the type found on many transistor radios of the time.
This circuit adds the voltage from the secondary of a transformer to an outlet connected to the...
We found this circuit in the April 1996 issue of Electronics Now magazine. The circuit uses a...
We found this high input impedance, low output impedance amplification stage in the October 1993...
