I was asked to make this Tweed desk module into a freestanding unit.

It utilised a McMurdo multi-pin connector on the rear to slot into the desk frame. I was unable to source a mating connector, and as I am a great believer in leaving vintage equipment as close to original as possible (in case it is ever required to fit back into a desk frame) I decided to manufacture an XLR panel and mount this on pillars on the rear of the module.

I then also mounted the McMurdo connector also on pillars inside the module so that I could use the existing hole to bring my new wiring into the unit. I was then able to attach my new wiring on to the existing wiring on the McMurdo connector.

I used the existing screw holes to fix my pillars which meant that no mechanical modifications have been done to the original mertalwork.
