Datasheet for valve sockets for PCB mounting?

[Dekatron]

I am looking for datasheets for the valve sockets in the photos so I can make PCBs for them. Using a caliper I get something like 15mm pin circle diameter for the small 7-pin socket and something like 17.7mm pin circle diameter for the large 9-pin socket - but since the pins are loose and wiggle about I am not sure if those are correct.

Does anyone know what manufacturer made them and does anyone have a datasheet with measurements that they could post here?

Have you tried putting a valve in the socket and then doing the measurements?

I can't find them in a quick internet search and the logo on the top is hard to make out.

[Dekatron]

Thank you for the idea of putting a valve in the socket and taking some measurements, will do so!

I put the socket in my scanner to produce a scan of the logo and drew the logo in red beside it as good as I could - maybe that will help?

Also if the pins / sockets are that mobile, slightly put in a valve while soldering to the PCB.

[Dekatron]

Ah, thanks, another good idea to think of when soldering them in place!

That logo reminds me of Soviet/Eastern Bloc era manufactured stuff but still nothing coming up in searches.

And reverse image search tells me that socket is a 'chocolate'

Are the pins offset? If not take your measurements off the valve itself, the B7 valve data I mean. To check you have it right insert a valve into the socket, drill a mockup out of thick card or plastic and check.

Yes, the pins are offset, looking at specifications of the B7G and B9A bases both sockets seem to be some 5.5-5.6mm wider pin circle diameter.

I suggest measuring the plastic body rather than the pins. Presumably the socket manufacturer placed the contact locations in the correct positions. With digital calipers one reading will give you the pitch circle diameter and then a little bit of trigonometry will give you the x and y coordinate.


Place the very tips of the internal jaws of the calipers at the mouth on one recess, set display to zero, then measure to the outer edges of two opposite holes. Zeroing on one hole diameter effectively give centre to centre distance. The pins are equispaced (including the missing pin position) so the angle between them is easily know.


Hope I understood your question, sucking eggs and all that.

Turn the Logo on the picture 180-Degrees and it COULD show Cyrillic letters LP (ЛП)
Maybe this will trigger a >Gotcha< from someone.

I now realise I did misunderstand the question, however finding the median radial position and therefore the PCD of the PCB holes is still doable if the distance over two opposite pins is measurd with them pushed towards each other and then again with them held apart. The average is of the two distances will be within PCB layout tolerances.

The movement of the pins will cause bad connections to the PCB due to the valve forcing its preferred position. It would be better to make a big hole and glue the socket in at the shoulder.
Connect the pins to the PCB with short lengths of flexible wire.
