Tanks Frans
I will run the zip on secret computer (never connected to intraweb) tomorrow
In the mean time I am going to work from drawings
So I double check the lot.
I will post Bom I get once done
(things getting slow lately...)
Time for spatchka now.

When done reading the previous then start at this one http://www.sg-acoustics.ch/analogue_audio/ic_opamps/pdf/opamp_distortion.pdf
Got up at 6 am FiFI build bug realy got me
As neigbours may not be pleased with sound coming out of speakers at this early hour
I have started to solder bit an pieces to the boards.
Must say solder wise those get a most deserved 11 out of 10

Copied from the MPP-thread (it needs to go here (I think)) 🙂
You could glue the smd (using double sided sticking tape) to the middle of a dip socket/header and use some thin (silver?) wire to connect the smd to the pins, while working under a loupe.

Can't see anything wrong 🙂
BTW you need a resistor wire bender, I will post a picture of mine later today.

Yes I know never got around to get one
Still I am pretty made up with the smd welding😀
Now that I got around to it is pretty easy
Just a bit of solder paste on track and hold chip with crocodile clip
Just touching with wet solder tip does the trick

Here it is, the (c) FdW 'Wire bender' 🙂 it makes nice 'square'-bended, and 'un-stressed', very even (sized) bended-resistors.

Super cool... I will build one ASAP... I am actually working in a "Menuiserie" so I can have easy access to all sorts of wood and corresponding machines.... (I am also considering building a pair of speaker enclosures 🙂 )
There is one thing wrong, IMO you should first have done the full build of the raw, then the pre- and then the clean power supply, this to be enable you to test each step before connecting the next step. By building the input stage very early you risk (there is not much risk 🙂) it at every step of the way.
About SMD. I do like non-SMD, old school through-hole, constructions, and I like them spacy 🙂, not maximum compact. IMO spacy circuit’s sound better than very compact, as normal for SMD constructions, circuits.
Nice, I did mount my boards on nylon struts and bolts in the boxes, then the boxes are mounted on separate nylon struts and bolts to a 'floating' sub-frame, floating (not truly) by being flexible. Due to the high mass of the 2mm thick copper box the whole system is mass-dampened.
