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.
Recently acquired Trio (Kenwood) vacuum tube audio generator on Ebay. Did a Google search for schematic and got zero hits. If anyone out there has this information it would be greatly appreciated. Thanks.
