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 an amplifier that uses 6Z-DH3A this tube and would like to pickup a spare. I can only find them listed in Japan. Looking for a Japanese Tube supplier recommendation anyone might have.
