The presented circuit makes use of a common operational amplifier that must be powered by a symmetrical source. R resistors from 10k to 1M determine the gain and compression of the signal.
We found this circuit in a 1992 magazine, but it can be easily assembled today because the...
This traditional configuration was found in a 1988 publication. Its gain depends on the base...
The power of this small amplifier reaches 75 mW per channel depending on the voltage and the load...
