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.
Doesw anyone understand the info given about the transformer's EI core? What is T, S, L, and H? And what does that ominous resistor R between L1 and L3 mean that has already been showing up in the diagram in posting #7?
Very pretty. (response, and final output transformer physical presentation)
Looks like you've got excellent response all the way from subsonic to supersonic. As anyone in this forum will undoubtedly ask though … Well Jerry, how does it sound?
