I have no information on the 813's distortion when used that way. 
Have you found any curves showing the effect of screen voltage on 
plate current? The linearity of those would tell something.

Alot of external things affect distortion, the modulation xfmr is 
real important.

One thing I don't like about doing different things with tubes is 
there is
real info on running 813's triode connected.
What's the distortion values?

I have a Gonset G76 that uses zero bias and drives the screen grid
of a pair of 6dq6 tubes as modulators.
I don't think its real clean.
