Sorry vdi_nenna, it should only be a Joke , but I forgot the smiley ....
and wanted to put away the the discussion a bit from demanding more from Mike.
So often someone is doing something good and then....more and more....
I cannot do Eagle either and a friend made two boards in handwork at the weekend, drilling and so on....
So I was privileged

I'm glad you like the sound, Gerd. I credit the builder. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I thought it might amuse you guys to know that the prototype had a place for a fixed bias and some jumpers to configure it. I tried it and it's worth some effort, but not strictly necessary to enjoy the sound. I like to leave those tweaks for you steely-eyed and golden-eared missile men.
I'm sorry I haven't shared the PCB artwork, but it's absolutely riddled with jumpers and alternative routes for different things I tried. It would take a lot of time and effort to clean-up and make DIY-friendly.
That, plus I'm lazy![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
...introducing negative bias supply

I the case I should be this
"steely-eyed and golden-eared missile men."
You are at least a "Great SIT Head".......

..is that because e sits on top of a column when on holiday in summer to meditate on new designs....??
...sorry for the OT remark.

So I still try to hear Luminaria and to play a bit with the parts.
Of course I also changed the 440R source resistor to a Vishay TO-220. I did not really compare, it was only for the good feeling, sorry.
After some hearing I had the impression that Luminaria plays like in heaven, really it is like a sound paradise. You only have the fear to wake up.....![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
After some more time I thought isn't it too soft, wouldn't be a bit more earthly tension better...?
The Panasonic caps I had on the in and output were only the 100V version, a bit too low for the output in my case.
I ordered, inspired by Nelson's use of the PWA caps in SIT one and two, four PWA Clarity caps.
Of course the sound changed, more body and more "on earth"
I think that is my final status.
Do not take these lines too serious, you all know the tendency to take a foreign design and change some things to make "own territories"
