Re: Open Circuit 'High Quality' PL259
Greenpar stuff is still available; they were bought by Tyco which subsequently renamed itself "TE Connectivity".
Tyco [now TE] also bought AMP in 1999, and they also seem to own Greenopar now as well. Still worth paying for.

Re: Open Circuit 'High Quality' PL259
Good to know Greenpar are still available.
Does anyone know if the quality has been maintained? I refer back to silver plating that better belongs on a gravy boat and you can see your face in it! |

Re: Open Circuit 'High Quality' PL259
Just to close this out I had a go at modifying the PL259 internals, I put a shim washer to spread the load on the PTFE, a silver plated cut ring expanded as a sprung connection to the case and finally a 35 Deg chamfer on the ferrule to further expand the ring out on the case to make a good solid mechanical joint whilst also locking the PTFE and centre pin in place.
All good or so I thought .... I then find the centre gold plated pin is too long for some sockets at 13.5mm and bottoms out before the locking dogs engage. (Amphenol pins I measured are around 10mm) I could chop the pin length but then I measure and find the threaded barrel is too long and hits the chassis part of the socket before pulling up. This was the case on some of my commercial gear. Well that is the sad end of this journey - I have enough new old stock plugs to do what I need. But then again, I could just trim a bit off the barrel.... Pete |
