As my quest to a Salas DCG3 nears its end and most of my preamp already functional, it is time to go ahead with my off-topic side-notes (those that otherwise would clutter Salas original thread).
So I will post my mechanical etc. weird ideas right here, brag about going where so many others already have been, etc.
Comments, questions, tips, scoldings, all welcome!

Here's my latest challenge to finish my build: The pot's shaft being too darn short.
The Volume-knob's grub screw just barely had a grip on the shaft, but ultimately slipped off or let the knob hang off-angle on the last millimeter of that shaft, I considered 3 options:
2 or 3 comments later I saw the solution:
I widened the knob's hole and use a piece of 8x1 mm tube as shaft-prolongation (instead of a commercial shaft-extension).
To get the shaft to grip into the tube, I cut it and compressed it just that little bit so that it firmly connects onto the shaft. Insert that set into the knob, and fix it with the grub et voila!

- try to prolongate the shaft (sort of adding a shaft onto the shaft
- shorten the knob (file down 2 mm off the underside of it )
- bring the faceplate to a workshop and have it CNCed for arecessed Knob(s)

Another ongoing challenge: The LEDs. Haha.
I wanted to not glue LED's into the frontplate and wiring them up (wire-salad!), but still have 4 leds all over it: 3 source-indicators and a power-indicator.
Of course it was about a new toy too:
Light-conductors! 😍
This would allow me to group the wires near the selector-switch (I stitched together a protoboard), plugging the leds right into it and getting my 4 led-dots (power = 2 mm, sources 1 mm) gently lit through those "POF" Fiber light cable.
They're not easy to handle (ofcourse!), being a bit stiff I realize I need something to get them precisely placed onto the led!
While playing around, the question of the junction led-conductor arose:
what's the most efficient way to channel the light: frontal or lateral? Short answer: frontal. The light gets sucked in. When the led is on the conductor's side, a lot of it seems to be lost...
this ist better...
than that.
I should test it in that casing I'm building just to be sure...

I'm not yet finished. Although I hoped so.
Troubles with volume-control. (At least not with tribbles!)
I the meantime, because that thing's (a finicky Elma relay attenuator board) not working, I of course forgot to make pictures of the working LED's 🙁
I have to adjust brightness a bit, as the power-indicator is much less bright than the source's indicators. I suspect the conductor is not touching the led and thus catches much less light than the others...
My build? a crammed place. But once it works, I'll be proud of it.
