I'm just thinking about the potential for leaks. I have pneumatic switches on my hot tub controls and if they ever become sluggish, it's just a matter of unplugging one end and allowing atmospheric pressure to reenter the system.
Hey! on the other hand... I think you might be on to something here.... Fill the system with rotor oil with a little food coloring added. And... equip each circuit with a tee and a small needle valve to meter oil to the rotor bearings. Viola! A maintenance-free tuba

Current 'stable'... Rudolf Meinl 5/4, Marzan (by Willson) euph, King 2341, Alphorn, and other strange stuff.

If it would glow longer that an hour or two sure.
Maybe you could use electronics for the lighting. What happens if an optical fiber end in a tube filled filled with clear oil? Shouldn't the oil glow? Then you could use a rotating wheel and cycle the colors too.

Of course, that goes without saying! That's why yoiu also need one of these:
'course you could just pop open that sucker and let the neutron flux directly excite the phosphors in the EL wire...
The tuba valves of the new millenium are solenoid operated. Silent, fast as an atom, and only minor maintenance. (The SOVs I live with function 24/7 for years and problems are rare.) 12VDC power, lightweight battery pack, (think modern bicycle lights), I don't see any problem, other than having to get used to the idea of a truly electric horn. I'm not advocating it, just saying it is easily do-able, right now.

How much would that sucker cost. Still, could be a fun conversation piece.
Do they still make them, or was it just a '70s experiment.
