I forgot to mention this back when I posted my reply on this topic. It's a
most excellent suggestion and works well. One more suggestion is that you
leave the tube in the socket and tie the resistor to ground from the cathode
pins. This way you also take into account the input capacitance in the
tube. It works very well. Just don't power the tube up!
