Duty-Cycle Modulation

For class A tube amplifier simulation, there should be level-dependent duty-cycle modulation as a function:10.3

A simple method for implementing duty-cycle modulation is to offset the input to nonlinearity Eq.$ \,$ (9.5) by a constant, such as input RMS level times some scale factor.
