How 'bout something like this (attached)?
Of course not so blown out, and maybe another font. (The light in my office right now is not very conducive to digital photog).
If I clean up the edges, it could be made stylesheet independent. i.e. will work on pretty much any color background.
Ill see if I can get a better shot of the VFD in the AM.

Credit to the empeg guys for the shot of the empeg housing.
I pilfered it off their site, and cut and pasted the display from my own empeg.

Cheers,
