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 have a keithley 2015 coming to me and I wanted to know if anyone has experience with this unit, and also what's the best way to measure THD on a integrated amp with tone control and aux and master volume controls ???????
