I'm nearly done, everything assembled in the case. Everything works perfectly
Learned a lot building this. Like the fact that connecting the HV and LV transformers in series doesn't really work that well.
And that it is a good idea to disconnect the mains before using a knife to remove some shrink tubing from the IEC socket. I was leaning both my elbows on the chassis at the time, giving me a small shock resulting in me butting the blunt end of the knife into my forehead. Made me feel real smart and special. Luckily it was only one phase to ground, and the chassis is anodized and have a pretty high resistance.
I'm proud of this project because I actually finished it. Told myself not to start using the amp before the casework and everything else was done, unlike all the halfway done projects laying around my room. (like a DAC with no top cover etc)

The chassis and some of the neutriks are from an old never-finished amp, wanted to use the side heatsinks so I extended the legs of the 10M90's a bit.
Ordered wrong small heatsink for the PSU, had to slightly mod a larger one to fit. Powerbutton is ebay stuff, orange LED.
SQ on this thing is awesome. (007MK1). At first I was a bit dissapointed, the soundstage was kind of small, all inside my head, but then I remembered switching opamps on my soundcard (xonar essence STX) a while back. Switched back to good old Audio-Gd disceets and everything changed. Very happy now! Next investment will probably be a balanced Audio-Gd DAC, but for a while the STX will have to do.
I'm also very impressed by the KGSSHV Mini PSU, very stable and very cool operation only getting slightly warm after some hours of use.
I know nothing of electronic design, but would it be easy to build a small version of this with only LV for +12V and +5V for powering the soundcard?
Thanks to every one that has contributed to this forum for all the info and help, and especially spritzer for answering my noob questions!
