Raising the Vf with Ge clipping diodes

[benny_profane]

I've always been curious about a ge and si diodes in series. It'd be great to be able to raise the Vf threshold and retain the characteristics of germanium clipping without requiring two or three in series in order to do so.

What behavior can be expected here? Does it work differently for soft and hard clipping implementations?

Add resistance in series. Experiment with different resistor values. Start very low (~4.7Ω) and go upwards.

Thanks for sharing those. If I’m understanding correctly, the series resistor is to emulate the sound of Ge clipping by softening the signal limiting, correct? I’m still curious as to what happens when Si and Ge are put in series and which diodes’ characteristics are retained.

In series, the total Vfd is additive and the characteristics are averaged.
