I think this type of solution is the way its going but its not very neat compared with the ones in the link below.
I was actually trying to use the sleeve that came with the plug and then push the socket in the end.

I think I might manage using a longer tube and flexible hook up wire.

That would work...

Rigid is best as you need to fit a plug in the end and then plug it into the patch panel..

Those are the thing. How on earth are those made? Some kind of contact so its clamped together not soldered...

The TR-10 has no input resistors in its OP Amps. You need to put them in the ends of the cables as needed.
It’s a cludge but it makes converting an op amp to an integrator simpler...
