Methods And Apparatus For Variable Solid State-To-Tube Rectification In An Amplifier
First Claim
1. An apparatus, comprising:
- a rectification circuit operating to convert a source of AC power into a final DC power source;
a rectification filtering capacitance operating to at least partially smooth a voltage of the final DC power source, which exhibits a voltage sag and recovery characteristic in response to time-variant current drawn therefrom;
a power amplification circuit drawing power from the final DC power source and producing an output signal, for driving a speaker, having audible characteristics influenced by the voltage sag and recovery characteristic of the final DC power source; and
a control circuit operating to continuously vary, in response to user input, one or more parameters of the voltage sag and recovery characteristic of the final DC power source.
