The 4 by 5 will have higher voltage, but the tube will easily handle
more impact than a small tube. Every system needs to be looked
at in view of the total system.

There is no average plate choke. That is the problem with rules of
The most important thing is to not put a glitch resistor in the grid. It
belongs in the HV lead.
