RCA input socket lost its mantels

[Aragorn]

On my preamp I heard a very low noise as from a non leaded gramopphonewire.

But as I looked, I saw the 2  output sockets connecting the pre with the end were both black, no red or white cup around.

These cups shield the cable input I guess from interference.

When I connected a cable in one of these 2 bare black input sockets and powering the end amp , BRRRRMMMMM!!!

I made a photo.

On the bottom you see normal sockets and at the extreme right next to CE I think 2 blach sockets.

How can these be repaired or replaced ?

photo very dark. Bottom of photo rcas in a row. Ultra right, you still can see 2 black sockets for the output to the power amp. Just 2 holes but without the red and white ringed caps around the hole. Did I loose those wile removing the amp or did a cable tore them out ???

he worked frequently before. But of course with the correctly built of assembled sockets.

question is if they sell these caps. I saw enough of them for cables, but for the female sockets ???

I recovered one from another piece of hardware, I ended up with a cylindric copper cup with a red ring. But i could not insert it deep enough along the hole , i was stuck ... of course the cable took it out again with no results.

zoom the photo in. It gives you a far better sight. You will see the cuts in the black socket rings.

lot of talks for a lost copper cup, cylyndric. 

 

Thank you.

Aragorn.

The fit should be tight enough you could still retrieve them from the offending RCA cable (if that was the culprit).  Even then the most realistic option is having these two RCA replaced.  

 

Though the picture shows for me it is quite uninformative.

 Agreed. I also looked at the picture but is not revealing enough to really  offer any informed opinion.

I think that there might be a message here.

Hi  Allan

The problem here, is the need to get behind the equipment to take a clear photo, and this would involve dismantling the whole set up.

That may be true, Alex, but a photo that doesn''t clearly show the problem to others is no more helpful than no photo.

Now that I can see your pix, it is clear that you get all that noise because the ground connection parts are missing!  You need to replace the dual-jack assembly.  It looks like something relatively standard part that has three contacts that can be unsoldered and resoldered to the new one.  LIke this:

That Peavey part to which Kal provided a link might drop in if the mounting screws are spaced right.  Unless you can buy an exact replacement from the manufacturer or a vendor, you’ll probably have a hard time finding another jack set that will seat properly and be securable with the original screws.  To force fit an inexact replacement, you may have to cut / drill the panel and/or use high tack mounting tape - and neither of these is a good idea.

 

I can’t see the whole panel in your pics, so I can’t tell if one or more of the input jacks is an identical piece to the broken one. From the screw pattern, it looks like the input jacks are a single assembly, in which case you can’t just short & insulate the leads to an unused input and move it to the output location. But you could disconnect the input leads from one you don’t use, leave them shorted & protected in place, and move the output wires to that pair of jacks.  If you choose this solution, be sure to label the new output location!

 

The rest of the RCA jacks on that unit are probably made the same way and the same age - so they’re  prone to the same failure.  The cause may have been the cable ends, the construction of the jacks, corrosion, etc.  Crimping the plug shield to make it fit more tightly can cause or contribute to this failure, as can leaving lower quality fittings undisturbed for a long time. This also happens when high quality, tight fitting plugs are inserted into jacks of lesser quality that can’t take the required force for removal.
 

Unless you figure out why this happened and do something to prevent it, you may have the same problem with other jacks on that unit.
