Asymmetrical Clipping Explained (PROOF From a Triode Datasheet)

Описание: In this video, I take asymmetrical clipping out of the realm of “tube magic” and prove it directly from a triode datasheet.

Using the grid curves from a 6N2P dual triode (a close relative of the 12AX7), I step through the full mathematical process of converting datasheet curves into equations that describe a real tube gain stage. By extracting polynomial coefficients, defining a load line, and solving for the operating point, we arrive at an equation that directly relates grid voltage to plate voltage.

The result is a clear mathematical explanation for the asymmetrical clipping behavior that triodes are famous for — including the pointed lower half and flattened upper half of the waveform. I then compare the math to real bench measurements, showing how closely the model matches an actual tube circuit.

This work also explains why a four-quadrant multiplier (ring modulator) is such a powerful building block for analog tube emulation. Once the math exists, it can be implemented in software, embedded systems, or even analog “computing” circuits to model classic guitar amps like a Fender Princeton, Marshall Plexi, or Dumble — straight from the schematic.
