[Amps] Plate Choke Resonances

[Larry Benko]

Let's talk about facts and not experiences or memories!

1.) Every reasonably complex electronic product designed is simulated 
beforehand
2.) Simulation software is extremely accurate if the actual circuit 
built (including strays etc,) is included and if the models of the parts 
are correct
3.) Vacuum tubes are devices that can be modeled
4.) A parallel resonant circuit (such as the plate choke) can have 
increased current flowing in it at the resonant frequency based on the 
loaded Q of the circuit
5.) To simulate the plate choke properly might need several inductors 
and distributed capacitors

I still believe that the loaded Q in the plate choke is not that high 
and consequently the increase in current in the plate choke is not that 
much and that serial resonances are what we need to be concerned with.  
This forum should be about increasing knowledge rather than telling 
people how they just never experienced some magical event that is too 
complicated to simulate.
