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.
Do you have a schematic for that "Darling" amp you built with the 717A tubes? It would be much appreciated if you could post or e-mail it to me. Thanks!
Hello, I am not Gerd but I described the amp, built this amp two times, the last one with slightly modifications. When you have ever any questions please ask here in the forum. I will try to answer. Pictures of the second variant are showed here.
Bye and best regards
