I have a few questions regarding plate voltage and AC load.

RE: any audio tube guys here?

I have no chicken entrails to peruse in an effort to divine your questions.

So ask them already.

(OP)
alrighty
PP EL34, fixed bias,
given varying plate voltage (200-400Va-k), and screen voltage following by a few volts (via screen resistor tied to OT CT), does the plate load vary much w/ varying Va? How much over 50V variation? How much over 100V variation?
I'm just looking for ballpark number....

Right now, I have a 3.4ka-a OT into 16ohm load...450V on EL34 plates, but I want to reduce plate voltage, and know the resulting reflected impedance variation. Again...ballpark numbers

TIA
