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.
Does the basic schematic for the Dodd Audio battery powered tube buffer exist anywhere? I am curious how the tube is run on the 12v rail. Would like to see the basic tube circuit used for this tube.
Thanks,
Jeff
Sounds like a relatively straightforward cathode follower with fancy components. HV can be made out of 12V DC using an inverter/smps and some filtering. I don't think it runs the plates on 12V.
