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 recently rebuilt a Magnavox console amp into an RH84 and am so pleased with the results I would like to build an integrated amp version with 5687 front end(5687 circuit on diyparadise).
