I can confirm the circuit of Tombo does work in combination with a Bourns em14 encoder.

Very nice.
If you will use massive aluminum volume knob, apply a smidge of Teflon grease at shaft, where it enters encoder, speeding it with rotation and exercising pushbutton action. With a very heavy knob, it could squeak a little after some time.

I apologize for being terribly lazy, but does someone have an updated/recent BOM (Mouser/RS Components)? Am having difficulty finding all the parts as some are no longer in stock. Thanks 🙏
Here we go, Mouser BOM for 1x uC and 2x Vol boards, i.e. the balanced/differential v2 version 👍

It would be better to DIY newbie like me If there are labels of components on PCB silkscreen in BOM.
I couldn';t find omron relay in Mouser or Digikey, but have bought omron G6K-2P DC5 relay on a local device shopping website.
I'm in South Korea.

I've found other links.

Hey Daniel, got a question regarding the v2 uC and Volume boards:
Thanks!
- For the uC board the pdf manual says C7 47uF/10V, however there is no C7 marked on the board, only up to C6?
Actually there is a 2nd C6, it is SMD cap right to the ST processor.
- For the Volume boards for C1, C2 the pdf manual says 180μF/25V but the Reichelt order number for this position is "RAD FR 220/35", which is 220uF/35V cap. So, is it 180 or 220uF better used?
Thanks!

Compared to a traditional analog pot, what would be the resistance that the amp would see by using this pot? Forgive me if I have missed this somewhere... thanks!
Could be interesting: https://www.diyaudio.com/community/...ncoder-for-muses-72323-volume-control.390237/
When paralleling multiple boards as multichannel volume control, is it possible to preset attenuation individually per channel or per channel pair to equalize different amplifier gains/driver sensivities?
