Aha! I admit I really didn't research the 6922 very much. I just have one 
(and have no clue where it came from. It was made in Holland and has gold 
pins though).

However I have a number of other "frame grid" tubes but  I think they're all 
pentodes. I remember hoping that these where sheet beam tubes when I read 
about the beam modulator on Ken Stone's web site. Only because I could not 
remember precisely what they were called so I had to go back and look them 
up again. I have all kinds of pentodes. Some of them are pretty weird 
looking.

But of all the tubes that I have the one I want to mess with the most is the 
one I can't seem to find: a round magic eye tube. It was the VU meter on a 
very old tape deck (that I lament leaving in a place where it could get 
flood damage :-( )

BTW, I enjoyed your page on VFD modulator very much! At first I thought well 
why would I want to do that? Which quickly changed to well hey that's 
actually really cool! And I have a whole bunch of those things. One of them, 
from an old Scott tuner, really screams and sustains (the susTAIN!) when you 
tap it. You can hear it from across the room. Now all I have to do is find 
some magnets. I thought I had a whole bunch of them somewheres. (Stuff gets 
lost really easy when you share a 3 bedroom house with justa cat and a dog. 
That cat is always playin' with my stuff and eating the food in the fridge 
that I CLEARLY wrote my name on...)

The thermionic reverb? Also very cool.
