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 this Bell and howell amplifiewr and would like to power it up. Is this connector familiar? How can I determine connections without schematic or disassembly? It is very condensed inside.
