Hi there,
sorry for newbie question...but can someone explain me how to calculate grid-stopper resistor in a class AB1 push pull power amp for guitar?
I mean If I have the data sheet of the tube (pentode) I want to use..
how can I calculate my grid-stopper resistor?
Typical values are 1k, or 5.6k..but which constraint on vacuum tube data sheet must be respected in order to choose this grid-stop resistor? I'm trying to understand the criteria to calculate it and the impact on the sound (I think RC coupling with grid capacitance so a low filter).
Thanks in advance.
