Anyone got a link to a picture of a glowing 12ax7 - I want one for some art for a stompbox. Tried searching in google for an hour or so and couldn't find anything useful

Sorry, not a 12ax7, but this picture is awesome!

Hey, I've been searching for about 40 minutes, and I can't find anything either. I searched for 12ax7, 12au7, 12at7, all sorts of other combinations, and other things. Nothing.
I remember browsing the Ampage Homebrew Amp pages a while ago and seeing a site where someone took neat pictures of glowing tubes in the dark, but I just looked through a ton of those pages, and I can't find it. Sorry. Does it *have* to be glowing? :)

I didn't find a pic either, but look what I DID find! a shitload of tech stuff on tube design. http://www.tubecad.com/
apologies if everyone knows this one already.
a bit off topic...
when I got my marshall, it had 5881 valves- they looked EXACTLY like that photo above. After I had it converted to el34s, the valves just have an orangish glow. Why is that? Can I get the blue/red glows with el34s? I am embarrest to admit it, but I really miss seeing that :(
Cheers,
Luke
maybe someone from one of those 5E3 forums could take a picture. That mission amps beginner project has a 12ax7.

BTW- i have saved that photo and its now my background! thanks!

...glowing, but not against a dark background...
Good pictures, try copying those into Paint and press CTRL+I to invert the colors. Looks sweet. Sorry, I don't have a way to post my own pic.

Very good! How did you find those? Or did you already have them? In any case, nice work!
