Wow, what a drag to hear. Are there any similar American made end view
tubes? This clock has to get out the door.

No, I didn't. Turns out I did do sorta that yesterday. I discovered I had
swapped the anode and cathode wires, so I switched them back and then ran
'em at about 1mA for 1/2 an hour or so. I read and will re-read the page you
linked, but any guidlines on these tubes? How much current and for how long?
They are at least working again. Thanks!
