    You can tell what the input impedance is on your volt meter by what voltage you get at the grid on a cathodyne PI. If you get something around 3V to 5V, then you have a 1M input impedance. If you get something around 17V to 22V, then you have a 10M input impedance.

    There is no need to resolder anything. Just get a new volt meter with a 10M input impedance.

    Whoever put 18-20V for the grid of a cathodyne didn't know what they were doing.
