John -Do you have any way to measure distortion (other than ears)?
I hate to be an engineer here, but...
I played with the 6AR8 a little as a phase splitter. I abandoned it because it had pretty high distortion, like 1-2%.
I didn't work at it, though, so maybe I just had a bad operating point or wasn't doing something right. I think I was also using it at a faitly high level (like after a 10x gain stage) so maybe I was just trying to drive it too hard.
The curves look pretty darn linear, so I wonder if I wasn't doing something wrong.
How much gain do you get?
