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.
Anyone who has measured the Ua/Ia above 8mA and 24V that is shown in the datasheets? My AVO isn´t working at the moment. Even if the tube is highly unlinear it would be great to have the curves.
