Good morning/good evening.
Here I am for the news:
I took apart the Sony power supply and double checked the voltages and electrolytics, used a couple of voltmeters to verify that the voltages were present at the same time as the power up and everything was running consistently. I also checked the -5V obtained on the analog board from the -12v coming from the power supply, and that works fine too. Finally I looked for the peaks with the oscilloscope but all the voltages seemed "clean" to me. This is what I managed to do in this period, in the meantime I ordered the ceramic capacitors from lopgica (104z and 103z) which I will mount as soon as they arrive.
For now, Happy Easter everyone from me and the SE with its Easter Egg!
