Theory: Ic/Ib = h21.
Now I have three BD139 transistor models.
The first one model - works perfect in all amplifire simulation.
Next two models works, but when I use them in amplifire simulation - my amplifire not works perfect - they are not perfect.
The question is:
- when I have three different models of BD139 transistors (or others) - is easy way to count transistors h21 - to buy real I need?
