(quantities will be updated after tomorrow)How did you switch the positioning pins?
Can they be pulled out, an jammed into the other posttion?
... Yes they can, just make sure you buy the ones with holes in the back for the positioning pins.
I opened my box of Yarra cases today. I have to say, I am utterly impressed with the quality of the work. I was not prepared for the sheer size of the box. It looks more like a Class AB power amp case. The front panel is thick thick thick machined aluminum. The lettering paint is so thick it raised. Anyhow, thank you to JPS64 and his wife for making such an incredible professional case available to us.
Some dryfit tests... the case fits together very nicely and countersunk screws are nicely flush.
The front panel is very thick 10 mm aluminum and has a countersink for the volume pot knob. However, the countersink depth may not be deep enough for some pots.
The RK09 that I usually use does not fit, but the Alps RH2702 stepped attenuator does have about 2 threads to work with. If you have a pot with a long threaded shaft collar,
that will work out better.

I wasn't able to get the Alps or the TKD pot threaded to the front panel after mounting the pots to the PCB adapter. Ideally the panel would be countersunk even more, etc. For now my shaft is floating and I'll count on the inset knob to stabilize further. I have the little pot boards on headers to facilitate swapping (i.e., not soldered to the main board).
The rear I/O board will also need some center support to avoid flexing when attaching/removing tight connectors. The RCA spacing is too close to fit all the nuts.
Not complaining, just pointing out for upcoming assemblers....

I am ordering these to try, they might help since they are skinnier.

But if you have not bought the RCA jacks on the BOM, these made by Manley are very low profile.

Low-profile jam nut is a potentially great solution for the rear!
I was thinking of a pair of round nylon standoffs midway along the I/O pcb with a notch to secure the pcb edge. Or a purpose-built pcb edge holder.

The Manley RCA jacks fit the rear panel with the mounting nut. Since they are individually mounted the pcb is not stressed when attachment/removal of interconnects is done. They need to be soldered to the pcb with short lengths of small gauge solid core wire for signal and ground.

Good news about the those skinny RCA nuts - they fit (almost exactly). You need to screw them on before the connectors are soldered in place to allow a bit of wiggle room.
