# Mystery Phototube connector

Can someone identify the type of connector this is and tell me its proper name?

• Looks to me like it's just a tube socket. Weirdly high number of pins, but maybe that's normal for phototubes. Jul 16 at 0:14
• Have a look at these guys for Photomultiplier tubes / bases. sphere.bc.ca/test/photo-tubes.html Jul 16 at 0:55

This is not a direct answer to the question.

It is a rough guide of how to find such a socket.

I did an image search for 19 pin nixie socket because I am aware that nixie tubes have a lot of pins.

One image of interest shows that you could make your own socket.

A review of the other images yielded a 17 pin socket named B17A.

Your socket has 19 pins, so an image search for B19A socket yields https://duckduckgo.com/?q=b19a+socket&iar=images&iax=images&ia=images

Here is one such image.

EDIT: One webpage has a module with a circuit. The module is called voltage divider.
