Found in a 1964 Electronic Design, this circuit protects the transistors of a complementary output stage. The diodes limit the current in the complementary pair.
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...
