I have an issue that makes me nervous a little bit. Very obviously all my NS2EX sockets that I use regularely (sustain, control, ch1, ch2) seem to get worn out more and more. What I mean is that the plugs are mechanicaly not hold tight by the sockets anymore but seem to be very loose. I‘m afraid that one day at a gig a socket stops working.
Does anyone have the same experience?
Would you recommend to exchange those sockets before there is a real malfunction? As I‘m an electronics engineer I could replace those sockets on my own.
Might as well change them before they fail. Do you use straight or angled plugs? I think the latter avoid to some extent the lever effect on the connector, but maybe that is only my perception.

Specially at home I use angled adapters (and angled cords for power, USB, MIDI) so that I can put the keyboard up to a wall without putting strain on the connectors.
Same here. Just a comment: for those making their own cables avoid the "pancake angled jack" style plugs as they are too wide at the base and interfere with the connectors next-door when they are not well enough spaced (i.e. you cannot put one next to another other in some keyboard back panes, because the holes are too close).
On top of that, the ones I came across seem to have the wrong profile of the tip 'neck' (too short compared to others) so the plug never locks in completely when inserted and tend to unplug themselves at the worst possible moment ( has happened several times with a sustain pedal in a MODX). This is quite surprising, I would have thought that the profile is pretty well standardised (well, it isn't ).

Hi Eumel,
I recalled a thread about someone replacing their output jack. The part number then was Switchcraft RN112APC (although Pablo recommended checking the part number that ought to be embossed on the device). I looked up the datasheet: https://media.digikey.com/pdf/Data%20Sh ... Series.PDF
In the drawing above, it shows a view with "cover removed". --This suggest the possibility to try removing the cover in-situ, bending the contact wipes to re-tension them to see if this improves the socket's ability to retain the plugs.
I don't know if this is possible, but seeing as you are an engineer, I expect you like to take things apart... and hopefully put them back together.
I know the difficulties of de-soldering through-hole parts from a multilayer board, so this might provide a less difficult interim solution.
Let us know how your repair goes if you decide to proceed.
Best regards,
pterm
