Hi,
this great preamp from @xrk971 has only a GB-thread, so I thought it would be cool to have a build thread too.
Even if I'm the only one who builds it AND publishes the progress 🤔 I hope with this thread to motivate the others who also bought the board.
This is there original opening post of the GB where X announced the amp (which is part of a great commercial amp)

I have the board since many months, but I have so many projects, so it took some time to start with it.
In the first step, I temporarily wired the board on a test bed to simply test whether it worked and of course to hear the sound.
And it sounded very promising.
So I decided to go all-in (or very-much-in).
Chassis work began, but as it happens, more ideas came up during construction... volume with remote control... but then I need an internal 5v converter, so I have to make a pcb... input selector with RCA and XLR inputs, but then I have to make another pcb... I made my last pcb about 30 years ago... so I planned it the old fashioned way on paper, drilled holes in the board, then drew the conductor tracks with a permanent pen and finally etched them in FeCl3. Flux and cover with solder, done. It's a lot of fun and can be completed quickly.
As you can see, the chassis is a combination of parts from @Gianluca and they will be combined with custom made front and rear panels.
And here the current status from today: SMPS, 5vdc converter, input selector, remote control and amp board working great.
Next step will be completing the chassis, and wiring everything together. I enjoy this project very much 😀

Getting closer to the finish. All PCBs mounted and wired, everything works fine, now waiting for the chassis parts until next week.
Hi again,
some progress, the rear panel is finished, connectors wired:
