This sounds very interesting. Particularly since I have 3 
ea. 5692 tubes which apparently are extremely high grade 
6SN7s. Phono preamp maybe?

Yes, welcome Eric!

BTW, I have been thinking about tube generated noise, has 
anyone ever investigated the neon lamp as a noise source? 
I would think that something similar to zener noise might 
be present there, possibly with regulator tubes as well. 
Gotta try a few experiments here!
