Small-signal circuits

[überfuzz]

Does anyone here have a small-signal circuit for pantodes and tetrodes? (I seem to remember using a FET small-signal circuit for triodes back in school.)

Cheers!

Here you go.

Here you go.

Thanks!!! You got the pentode too?

The model works for both beam tetrode and pentode. The various parameters need to be fitted to the individual tube types.
