Using a Motorola MC1684 integrated circuit this 1968 amplifier provides 1 W to a 8 ohm load. The response ranges from 20 to 20 000 Hz and the distortion is only 1% at 1 kHz.
This circuit was obtained in a 1975 documentation. The maximum frequency depends on the diodes and the...
Found in a 1990 Hobbyst Handbook this circuit has an output power of a few tens of watts and...
The circuit shown is a constant current source which allows the reading of resistors on a very low...
