Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

You may be right

but I never read anyone talking about a grid stop resistor in this thread.

Of course the larger the grid stop resistor the more highs one will lose.

The grid stop resistor is in series with the source impedance and adds to it directly.

The original poster ask "grid resistors first stage of amp
What value do you use? The Max resistance stated in the tube datasheet? Say, the input of an amp, I've seen commercial buffer stages use 470k grid res."

Nobody I know would use a 470k ohm stop resistor.

Thanks

BTW I use the smallest value stop resistor that will do the job.
