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.
Would anyone in the USA be able to run a tube through their curve tracer? Nothing crazy or anything just a 9 pin dual triode. Send me a PM and I can fill in the details. Thanks.
