My preamp has some generic gold plated RCA panel mount jacks I purchased from an eBay seller in China. All my cables fit them very loose, seems they must be a bit undersized compared to what is on most commercial products. I just gave those generic cables that come as standard with most products. I know, what did I expect but I did go off of a link someone on this forum posted who said they function just fine. Anything I can do to tighten up the connections? Giving the cables ends a squeeze with pliers doesn't seem to help. Do better cables have tighter connections? Anything I could use to bulk up the connectors a bit?
The single time a fuse blew in my amp was when a junky RCA plug broke. These days I splurge on fancy Neutrik Rean RCA plugs and sockets at over $2 a piece.
I can't offer any practical solution other than to replace the RCA sockets with ones from a reliable supplier. Sorry!
Spiggs,
JK Electronics in Westminster used to carry locking RCA plugs. After you insert it in the jack you twist the metal sleeve and it tightens the prongs around the jack. Swing buy to check if they still have them, get a pair and try it before soldering it. If it works they also carry good quality coaxial cable by the foot, so you can make new interconnects.

Thanks grimberg. That seems like a possible solution. I'll check out JK Electronics and see if they still have locking connectors.
I've found a couple of batches I bought from China recently have been loose. As you plug the RCA lead in and give it a little twist to get it to couple, the inner core rotates freely which stresses the solder joint.
I buy quality ones from places like Farnell / RS etc. now.
Those locking ones sound interesting.

That's some interesting info avtech23. I am also having some random noise problems with the preamp the loose connectors are on. Perhaps related?
All cheap RCA connectors are horrid, but then all RCA connectors are a disaster anyway - just get the pliers out and make them a little oval for better grip, standard practice surely?
Decent and cheap locking RCAs are the Onix sold at parts connextion.
Excellent quality
Mini xlrs should have been the standard but it is what it is..,.

I've had same issue going back 2-3 years. I think it's imperial-metric errors.
The problem is now on 3.5mm PCB jacks too.
Using nos rca cables will oversize the current China offerings.
The inner conductor becomes loose.
high end mfgrs must have some way of dealing with it..
