This 8 ohm output amplifier was found in a 1968 Motorola publication. The circuit uses transistors of the time and is powered with a voltage of 25 V + 25 V.
Using the 4001 integrated circuit, this latching relay can employ any general-purpose transistor. The...
Suggested by a 90s Electronic Design, this circuit drains only 0.25 mA from its source. Listening...
The frequency of this oscillator depends on the amount of light incident on the LDR. The circuit,...
