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'm looking for the Glass Audio 1/89 article by Joe Curcio about his Dynaco ST70 modification. I have a old photocopy that has faded over the years (yep 45 years ago). Can anyone help? I sold my Glass Audios years ago.
