WOW !
Why they do not vaporize instantly, then ?

Hello Bill,

Your assertion is only true when there is no RF on the plate. When the tube
is driven to full saturation, there will be nearly + and - 1200 V
alternating across the parasitic resistor.

That parasitic surpessor is not across the B+ supply to ground. It is in
series in the plate circuit so 1200 volts B+ on one side and um...pretty
darn close to 1200 volts on the other end. Just keep the golden screwdriver
clear of it ;)

Bill  KU8H
