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 listened both Voskhod manufactured and Anod factory manufactured 6N1P-EV tubes in my preamplifier. I have noticed that, Anod brand 6N1P-EV impressively much better sounding. Anyone have similar experiment with them?
