Anyone know exactly what this parameter is. It seems to effect the HF response.
Does it have to do with Miller capacitance?

Cliff are you referring to the cold clipping stage or the stage right before the cathode follower stage?It sets the cutoff frequency of the resistor/cap combination on the plate of the last triode stage (the previous stages are not user adjustable).
Most amps have no cap on the last stage but a few do. You can vary this parameter to simulate increasing/decreasing the capacitor value. The frequency is only approximate since the actual frequency varies with the bias point/cathode impedance/drive/etc.

I ran the 1st 3 posts through Google Translate, but it didn't come out with anything.
Which language was this again?

So... what does it do (soundwise)?
It will give you some control over the high harmonics that are created during clipping. The cap in question forms a low pass filter with the plate resistor on the triode stage. In English, it will allow you to control the buzziness that sometimes occurs with higher gain settings. It can also serve as a gain dependent tone control of sorts.
