Info on this socket?
I was going to ask what it is and then I found out.
It is called JS/1/PF and even has an Air Ministry number 10H/4953 It's about 14mm diameter (approx - hard to measure) at the threaded part and the pin is about 3mm diameter. So where do I go to get a plug to fit it? And does anyone have any info on it? |

Re: Info on this socket?
Hi
From your description and the picture I think this may be what I know as an "F & E" (Films & Equipment) connector. I believe that these were originally used on projection equipment for the sound O/P (this may be incorrect but that's what I heard). I have a number of B40/41 receivers and this connector is used for the RIS I/P and IF O/P. They are not common but can be found if you know what to look for so I hope that attached pics are of assistance. Regards Terry C (ZL4TC) |

Re: Info on this socket?
The snag being that one cannot "look" anywhere these days.
So no idea where the pictures came from? |

Re: Info on this socket?
Is it the first type shown in the attached datasheet?

Could you post a non-encrypted version of that PDF please?

Re: Info on this socket?
The PDF file isn't encrypted. Might be a problem with your pdf reader perhaps?
The one that Andy highlights looks very similar to the ones in Terry's photos. Richard |

Re: Info on this socket?
OK, I found something that reads it.
It is encrypted with a rather modern method that most readers cannot process. And yes, that first plug might be what I am looking for. Any ideas of a source? Well maybe, the pin looks a bit thinner than needed Last edited by GMB; 25th Nov 2020 at 12:01 am. |

Re: Info on this socket?

Re: Info on this socket?
Head out from under sink, have found three off F&E 10H/19698 (males) and also a hefty double-ended female link marked F&E JS-1-DE.
The pins do indeed seem to be 3mm approx, and thread difficult to measure but seems to match your figure. Knew i had them.. PM me your address and which bits you want GMB, and i will calculate the postage (probably a slim box rather than a jiffy as i don't trust them not to break out.) Dave |

Re: Info on this socket?
In my case, I am trying to connect to the Post Office Engineering dept's "Measuring Set R.I. No.1".
Being an accurately calibrated thing I am reluctant to hack it about just because the connectors are almost (but hopefully thanks to Dave, not entirely) unobtainable. |

Re: Info on this socket?
I remember that type of connector being used in some of the old commercial test gear that was still being used at Plessey in the early 1970's. I always wondered what it was called.

Re: Info on this socket?
I recall using these connectors (we called them "Small F&Es") in the late 1950s , and what are now known as" U.H.F.s", we used to call "Large F&Es" !
In case anyone else is desperate , I still have a small quantity. When soldering , beware of those with polythene innards ! Laurie. |

Re: Info on this socket?
Many thanks to The Philpott who has kindly sent me some examples.
They seem rather nice plugs. I wonder why they were not so popular. Mind you, I haven't tried soldering them yet - I can see the polythene inner being a problem, just as on the TV coax plugs I guess. (They are not the same the so-called UHF type commonly used today.) |
