The integrated circuit used in this amplifier is uncommon today, since the project is from the 90s. The power is 24 V, and the gain of the circuit is 40dB. The input resistance is 1 M ohms.
We found this circuit in a 1977 Radio Shack manual. The light bands are given by the operating gain...
The circuit in the figure is a current regulator with adjustment in the range of 0 to 3 amps. The...
This stage for JFETs was found in a 1965 US publication, but is valid for modern components. |...
