[AMRadio] 4D32 rig testing

[Brett Gazdzinski]

Don,
Well, so what?

Collins runs them at over 700 volts in class C plate
modulated service (32V series).
If they don't arc over, and you don't exceed the plate dissipation,
what would be the problem?

I am also running 812A's and 811A's at 1700 volts or more
without any problems, and some run them at 2000 volts!

Cant say I have had any tube failures in the last 20 years, 
or had any go soft/weak.
