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 am hoping someone has the Aikido CCDA 9 pin user guide .
Please send to me or post as attachment. Seems tubecad site
links are down for some of the manuals.
