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.
Hi All. I went to a surplus store yesterday and way in back they have rows upon rows of PIO caps (a couple as big as a trash cans). Do PIOs go bad? If so, how would I know? Cheers.
PCB based insulating oils are safe unless the capacitor is dismantled and if so then becomes hazardous.
They are perfectly safe in motor start/run metal cases.
Is that Jones Surplus on Central Ave.? I used to dig through the tubes and other "surplus." They had an EG&G factory nearby, EG&G was making the Krytron tubes.
