Hey, Be patient, now. Good things come to those who wait, patiently.
With the Very High Voltages underneath the Bogen, your calm, confident movements are needed !
When I was studying electronics, rereading stuff, over and over, while monotonous, was necessary. There is so much theory, that must be respected, and remembered, even if not fully understood. The best example of that, is the theories of how current flows. When working with tube stuff, or electricity, whether current flows from positive to negative, or vice versa, is not relevant. What is most relevant, and hardly ever mentioned in any theory textbook, is Never get in the way of that current flow !
For safety, don't be the conductor of that current. That is why the practice of one handed testing is imperative. Using two hands, and stumbling or fumbling, getting in the way of the current, there is a high likelihood that you could get the shock across your chest/heart. That could be fatal...
So, in the future, when really checking cathode bias, from cathode to grid, first secure the test probe to the cathode connection, using only one hand. Then, probe the grid with the other test probe, using only one hand. I might sound repetitious, but our health is important...Even one handed shocks are nasty. For those less confident, use leather, or thick rubber, or real high voltage gloves.
By the way, m80, thank you for the kind words. Best of Luck and Happy Listening...
