I don't think it is. I have an acoustic delay line, and it's
more like a coil of wire than a valve (vacuum tube). If anyone's
interested, I can put up some digital photos of it.
The gadget on eBay seems to have high-voltage electrodes at
each end, similar to valve anode caps. Looks like there are
glass-to-metal seals as well, so the interior is either evacuated
or filled with a low-pressure gas. if it wasn't for the label,
I'd say it was a Xenon flash/strobe tube.
