Early '80s Ibanez musician jack input MC924

[Bass Awkward]

Hi there,

So, I sat my Ibanez musician down on top of an audio jack...

Now the jack input is fritzy. If only it had just broken the sodding cable.

I've taken it apart, and tested the wires for continuity: the issue is within the sealed unit jack input. It's wiggly somewhere inside, and because it is sealed, I can't get in to bend the contacts and fix it.

The problem in replacing it is that it's a weird one. A giant switch on top of a mono jack barrel input, wired with a couple of diodes(!) to earth.

Including the rest, there are eight (!) pins on the sodding jack housing - presumably a DPDT switch, and, er...

I can't find anything [i]nearly[/i] like this, anywhere, and given the wiring, I'm totally unsure about trying to reconfigure it for a SPDT switching jack. I've even bodged a fix for one of the preamps in these bases before, but this jack has me absolutely stumped.

Borrowing an image from another thread - though for some reason I can't put this directly within my post:

Bought something like [url="http://www.ebay.co.uk/itm/1-4-Switched-Jack-Socket-Panel-Mount-Connector-JS01-/191347277226?pt=UK_Sound_Vision_Audio_Cable_Terminations&hash=item2c8d2fbdaa"]this[/url] as a replacement...

Edit:
Found a 9 pin input - fishman make one that is available through thomann.de, or there's a nice cheap one that Stewmac sell. These are fairly similar to the Ibanez part, and identical in configuration (and I suspect that the StewMac generic part is just rebadged for Fishman).

It just means moving the wiring over, essentially identical wiring on a different part. Easy!
