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.
Just a heads up.. EIFL's prices are really good for this stuff, it may be cheaper to go through EIFL then to have a friend go into Tokyo and try and buy it for you.
