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.
Both of these tubes came with neutralisation screen and I am just wonder that Could these tubes be used as a normal double triodes as ECC88?And from the data it seems that each section of the triode of the same tube have a slightly different electrical behaviors.
