I have in my collection of objects, my wife calls it junk, a 100 kHz crystal
in a package that looks like an octal base tube. It was cast off from
somewhere and is in an oven but I can't find a circuit that will make it
oscillate at 100 kHz. That is probably the reason it was cast off. An HP
wave analyzer, model number forgotten, used several similar appearing
crystals in the narrow band filter of the 100 kHz IF. Also the HP 3570A
network analyzer uses three of them the 100 kHz IF in each channel. It
wouldn't surprise me to learn that the same engineer designed the IF strip
for both instruments.

Subject: [time-nuts] Interesting looking crystal on ebay
This is certainly not time-nut standard, but I've never personally
seen a crystal like this.

I guess it has so many pins so it fits in a valve base.
