NON-LINEAR DIGITAL IMPLEMENTATION OF A PARAMETRIC ANALOG TUBE GROUND CATHODE AMPLIFIER

In this paper we propose a digital simulation of an analog amplifier circuit based on a grounded-cathode amplifier with parametric tube model. The time-domain solution enables the online valve model substitution and zero-latency changes in polarization parameters. The implementation also allows the user to match various types of tube processing features.
