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.
Yep, I think that they used the EL84 and 12AT7 models as the closest ones they had for simulation as they are similar. The 6LU8 actually can handle a couple more watts of plate dissipation than the EL84 but they seem to like similar loads.
