Problems with AV RCA jacks on Atari composite mod

Recommended Posts

Hi everyone. I have installed a couple composite mods on some 2600s and some of the jacks start twisting after I plug in and unplug the cables a few times. The jacks are tightened as much as I can manage to get them (and I don't think they will tighten more as the whole jack twists, not individual pieces as they do when loose). Does anyone know of a good way other than dumping glue on the jack to stop this from happening, or is glue my only choice? If so, is there a certain type that works best? Thanks!

They usually come with a lock washer and I put those on where they are touching / compressing against the case plastic and that hold them in place pretty well

 

If yours didn't have lock washers just any split washer that fits should help

Actually the ones that have the washers have been the problem jacks for me. The washer was between the nut and the piece you fees the grounding wire through. I will swap those around and hopefully that will do the job. Thanks!

If you line up and bend the grounding ring tab perpendicular with a flat on the holding nut, that will help quite a bit

 

If frequent plug/unplug operations is expected, a drop of super glue makes a great thread locker. But do so only after the soldered connections are made, otherwise fumes can leave deposits and contaminate your solder joints.

yea that's the configuration they come in but I found it works better if its case, lock washer, tab, nut

 

also you can gronk on them pretty good if you use like some grippy rubber (like they sell "jar openers" which are a thin rubber) to hold the outside and use a wrench on the nut. course keep in mind its old plastic and cheap brass (at best) metal in the jacks so don't overdo it

Great. I will definitely switch the washer around and bend the tab down. As much as I'd like to avoid glue, I think the super glue might be needed if they keep coming loose though. Thanks!
