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.
Can't help you on calculating the performance of the circuits. The numbers I have are from building the circuits and measuring them. I did have fun designing the test setup that was capable of measuring high performance CCS's with repeatability.
