pic 3 looks very like the hand drawn traces one found in 1970s manufacture, before CAD was allowed to take over our thinking. Very retro and nice.
Silkscreen corrections
Thanks for the extra eyes and compliments guys.I think i should change the default colour scheme in Sprint.The colours seems to merge in my brain after a while.
Corrections have been made to the silkscreeen,gerbers and lay file.

Thiago, Congrats!, thats a very nice layout!. As Bangla says, it should rumble some windows and houses..

I don't like, I love 
Congrats 
If you do more minor change, you could change the +/-42V on the silkscreen for +/- 50V just to match the schematic.
This week-end, I'm ordering the pieces for the regular Quasi.

Hi All
I haven't built anything for several years but I'm keen to start a new project. I've been following this thread and fancy etching my first boards. I'll start this tomorrow. I can make the under mounted fets work with my heatsinks, but it may be easier if they were located at the side of the board. Has someone designed a board that I may have missed? No worries if not 🙂
Many thanks
Richard

This thread moves fast! new layouts and now a Big Quasi...
Tonight I listened for 2 hrs with headphones and it does sound good.
I loaded the output with 7R 15W resistors and ran the 50R phones off that.
the first one was built with whatever compensation caps I had, mostly MLCC and closest value.
the second board uses wilma MKP and so thought I might hear some difference.
Square wave response shows some spikes on the side I used the correct value cap's.
the output coils are not installed, are they needed for testing? or just for speaker duty?
my understanding is they protect the amp from the speakers.
anyway Great thread, and Thanks

No, Max, not tested. However, I can guarantee 100% that it will work well without instability, BUT the big question is HOW good the SOUND is vis a vis the smaller Quasi......
