Thanks to Alkasar for the T2 guide in French:

I have written some time ago a “T2 mounting guide”. It’s in french. Download from here :…ent%20v2.2.pdf

It’s also valid for T1, and most of it for T4. 
It addresses general considerations; cabling with Connex SMPS300R, Meanwell S-350 or transformer; offset adjustment; pot bypass; grounding. 
Pictures will be helpful for non french speaking 

links to french forums where Hifimediy amps are discussed…f=1&t=29963955…056&t=29948040

The first link has a lot of pictures of mounted Hifimediy amps.

long live to this forum,
