Not always. In a cathode biased amp, the plate (anode)-to-cathode voltage is a bit less than B+ since the cathode R is dropping some volts. In a fixed bias setup, they are just about the same, as there is negligible cathode resistance to drop volts.

See Tubelab's comments in post 39 here:

True but based on my understanding of the question to view them as the same is the safe guide line .
I was answering it not as an absolute but as a good guide line for max voltage on this tube.
In this case 400volts the real plate voltage will be less because of your example and tubelab work.
I though the nuance of subtracting the cathode bias voltage would confuse the question as I understood it was asked. Regards

Triodethom: No worries, I was just attempting to further clarify things for imnewbie.
