OK. I don´t have a tube tester. How can I go about testing some tubes I´m selling for gas and leaks and shorts?
I built a simple powersupply and I´m matching the tubes for the same plate voltage, but this is as far as I have gone in testing those.
Everyone that bought some are happy, but still I would like to be able to test those for other possible problems before shipping, and also to test other tubes of my collection for my own use in my DIY.
I guess it´s hard for me to find one of those old tube testers here in Brazil, so I´ll have to DIY it, but have no clue about how to test tubes for gas and leaks... Shorts should be easy...
