Improving the Chinese Jung super-regulator

Hi,
I have got a Chinese PCB board and its called a super regulator by Jung, not sure if it is one of W.Jung's designs but it works quite well, I tried it with a NOS DAC chip, not a but result but it sounds very forceful, a bit too much of a good thing I would say.
I have drawn the schematics of it and it would be great if the design can be improved if can to be improved obviously 🙂.
...please have a look at it and add your comments.
best regards
K

yes, correct! I have got some of the original Jung/Didden boards and can't get them working at 5vdc at all, and the poor website that explains how to use it is so bad.
so many links to some old explanations and links to upgraded versions and links of links explaining how to set it to 5vdc, and every scenario is different!, and I got lost, and bought a Chinese version that has the pot, and it's easy to set the output voltage,
probably easier job to improve the Chinese Mr. Jung than figure out how to use the real deal thing.
 
I had the same boards a few years back, used them in two electronic crossovers, 3 way, they performed okay, I never really tested them.
If you have some equipment you should measure noise at different loads, I believe a oscilloscope, or even better a soundcard could provide answers

Did you read the article posted with the kit at diyaudiostore.com? What is unclear?

yes, I did manage to get it running, and to be honest, it does perform exactly the same way as the Chinese version,...sonically at least,
would you mind looking at the Chinese one and letting us know what you think?,
hopefully, I'm not being too cheeky -)))
