Periodic Volume Drop-and-Pop

I have been digging a bit further. All of the spec sheets I have found on the Type 36 tetrode show a maximum screen bias of 90V. However, the change of the 9kOhm resistor to a 13kOhm results in a screen voltage of about 120V. Even subtracting a 10V cathode voltage this is well above the 90V cathode-to-screen-grid values in the spec. I noticed that the Type 77 allows for a higher screen bias.

I haven't tried a 9kOhm resistor yet. I am curious to see how that might affect things.
