I'm near San Rafael

But its been a long time since I did any electronics - used to work on tube hi-fi, guitar amps, and the occasional TV - 40 or more years ago.

Is there any easy way to tell if the CRT has vacuum - aside from the filaments lighting up?

Small tubes I remember had a silvery coating that would turn to white dust if the vacuum failed ,,,
