Control of Amplifier Source Resistance
Many varieties of variable damping-factor control have appeared in commercial high-fidelity amplifiers during the recent past. This paper discusses and categorizes the different forms, introducing an analysis of a general nature that is applicable to all present configurations. General equations are developed for the design of any type of circuit utilizing current-voltage feedback control of amplifier source impedance, whether it be fixed, semi-variable, or continuously variable. A new improved type of variable damping control characterized by a broad range of adjustment and simplicity of circuitry is described.
