This circuit for FET was obtained from a 1977 Radio Handbook. The input impedance is 150 ohm. The output is high impedance.
This precision speed control was obtained in an Electronic Design from the 90's. The output final...
This amplifier for old record players has RIAA correction and was found in documentation from the...
We found this configuration with a logic circuit that is now uncommon in an 80's documentation. The circuit...
