I transferred the designs to the 500 format. Works perfectly and does what it is supposed to.
Hardest part was sourcing the C500K potentiometers. Initially I went for these
https://www.conrad.at/de/p/alpha-rd...entiometer-mono-0-05-w-50-k-1-st-2358971.html
However, they are C50K, not center detent, and limited in quantity.
So I only used them for prototyping and ordered a small production line of 150 pieces by my own. They are center detent and C500K and what you can see below and in the dropbox link.
Compared to the original build, Bands and the gain level of all bands as well as the overall gain can be adjusted.
For my builds I have tried to find potentiometer with similar/matching values, as they are 20% accurate to what is given, that takes a bit of quality control.
However, I'm very happy with the Build, and thanks a lot to members KHstudio and PeterC, who started the project here.
Here are some pics and the link to the building documentation:
