Thank you Jonesy for your input.
I knew that page. My regret is that they are mostly written descriptions. Photos work better when they accompany descriptive text, because there are some very subtle differences sometimes.
The information is scattered in several places. Honestly, I haven't bought tubes in years, so I'm getting back the links I used to have, plus books like Tube Lore and magazines like Vacuum Tube Valley. I'm a little rusty.
