I thought this is the chance of me contributing with summat simple but maybe helpful to others.
Ill try to document each of my finds as doesnt seem to be much about this series on the net.
My intent is purely educational as my intention is run through it and sort the "likkle" bruises she might have come across in the time of usage ( seems she had a good owner anyway: Let's say the PSU is a DIY recreation, but beefed up. But was kind enough to leave some labels on his DIY'ing, which im finding quite helpful).
Ill start by saying i can recognize some "Portuguese" TL071's and TL072's (including the nice eq which i find quite musical ; Im forced to say im much more impressed with this desk soundwise that id ever thought id be...).
So, lets start with the proverbial pictures.
