6BQ5 Bias Point Help
Is there a better way to determine bias point and grid volts for different Vg2 volts besides looking at the Vg2=250V curves and guessing?
Use the triode curves and you'll be close, since the current will only go up slightly with higher plate voltage.
Then all required combinations can be tested and the results are fully "live".
I see this as the best way if not suitable data is available.
I have used this method for some soviet-made output tubes with good results.
Ofcourse this requires that one has some test equipment available.
