I have attached three Mouser BOMs, one for each PCB.
Please let me know if you find mistakes, so i can correct them.
I was not able to find the encoder at Mouser, do anyone know of an alternative?
With a few components Mouser did not have the exact component Meldano have specified (either not at all or not in stock), then i found an equivalent.
For the 4148 0805 diode, Mouser do not have it in stock at the moment, however they will have it the 23rd of february. The rest should be in stock at the moment.

I have an issue with my boards. I located the encoder to the front plate with flying wires, not sure if that's the issue. In any case there is no music coming through and turning the encoder or pressing it doesn't doesn't do anything.
Measuring the power on the boards I seem to have +-15V and 5V in all the right places. I also checked all legs of the muses chip individually for continuity with its respective connections on the PCB and it seems fine as far as I can tell.
Any idea where the problem could be? Or any other tests I could do?

Hi,
is it possible to teach the remote control keys?
If not maybe a microcontroller problem...

Thanks Daniel for the quick response.
I just tried it and unfortunately teaching it the remote control keys doesn't work either...

First beta test with positive result and some bug fixes / improvements.
I will ship the first kits to the end of this week 🙂

Thought I should share my "finished" dcg3 line/HP amp with Meldanos muses volume control.
Everything works as it should now (I hope).
A quick fft plot also.
The controller and volume board is fed by +-14Vdc based psu (TPS7A4700)
+5vdc is taken directly (simplest way)
1kohm pot between 5v and adafruit display (for dimming).
Hade some noise/hum issues but I think I managed to solve those. For instance 0/gnd on volume psu had to be grounded good to chassis gnd.
Missing frontplate, have to make a new 😀
It plays beautiful

Is there any reason why I shouldn't connect the controller board to the muses volume board via ribbon cables, say 30-40cm long?
I can offer a small usa group buy with priority shipping.
A diyaudio member in the usa will collect and handle the shipping.
