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.
Please take a look at Jeremy Epstein's design.
2, 6C45's used as a Phono stage, and a 12B4 for output stage, this will be one I just will have to build.
