Dumpster diving save VFD

More lifespan/thermally rugged than OLED, wider temperature range (OLED really does not like hot ambient if you drive it bright, VFD doesn't care), they're fairly rugged to physical abuse, and they don't go blurry and slow in subzero temperatures.
But on the other hand high power consumption (makes it difficult for portable devices) and a relatively large form factor make them impractical in other ways.
Fun fact, Noritake make VFDs and fine chinaware for your grandma. An interesting combination of abilities.

Its not a stretch to imagine that the environmental requirements for both VFDs and fine chinaware are somwhat same.. :-D
long lifespan, rugged, wide temperature range and so on..

Yeah, here in Japan Noritake are known for various types of high grade ceramics both industrial and kitchen, and of course their VFD's, including the Korg Nutube.
Miti:
Do you have any source for a good filter, something similar to the HP34401 front panel, dark green, about 1mm thick, good transparency? I can’t seem to find any, but I’m not known for finding things.
Cheers,

Nothing that isn't available on Amazon. Grey smoked acrylic would do the trick.

I bought a pack of thin (maybe 0.8 to 1 mm) plastic sheets on Amazon, various colors. I think they called them acrylic but they were more flexible like polycarbonate. Used some for contrast filters on CRT oscilloscope, as well as VFD displays. My favorite color is "rose", kind of pale pink. It makes the VFD look white, by filtering out some blue and green. Can be combined with smoke for additional contrast. I've also used colored "gel" or cello or cellophane sheets, which are very thin. This needs to go in between the VFD glass and some other durable lens like acrylic.
