WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
I'm looking for opinions because some people seem to have their favourite bias points, and things aren't always as they seem. Other than that, I'd think you're right.
Hi !
6J5/6SN7/7N7: Stay generally above 9mA. The curves are VERY linear there.
I expecially prefer higher voltages. I have about -6V Ug1 and bit over 200V because of execellent linearty in this region.
