>Voltage regulation measurements would be nice.

I don't quote the figures because they're almost embarrassingly good. 
The output regulation, hum and noise are all typically below 100mV - a 
4-1/2 digit DVM doesn't flicker between no load and full load. That's 
certainly better than any power tetrode actually needs, but it's what 
the active regulator happens to deliver.

>Were the IMD measurement relative to PEP or to the two tones?

Relative to either of two equal tones, so they all look 6dB higher than 
the ARRL-style presentation (which is below PEP). More important are the 
differences between them.
