Kevin I tried G2 on the metal bell, no dice. I did find though that if I swapped the grid wires it would read full emission- that is, without G1 bias it simply read like a diode and it would deflect the meter but it's not quantitative. In other words it tells you there's emission there, but won't tell you how controllable it is. Guess something is better than nothing? I still say the ultimate test is in a running chassis, just like with the electrostatic tubes.


Sandy- darn tootin!
