Nino, where did you learn about electronics? Are you trained or did you pick this up yourself? While I understand the general idea behind electronics and all the components involved, I'm amazed at how well you know the ins and outs of each component and the relationships between them all. Fascinating!
It's all about learning troubleshooting techniques. I could troubleshoot EMs when I was 14 and Bally Bingos at 16.. By 18 I was Working on Juke Boxes from the 50's and 60's.. Even assisted a restoration of a Continental II by the time I was 25... By this age most kids that age were out drinking, modding cars and chasing tail.. I was more interested in Z80 and 6502 machine language programming ... Oh the memories...
I completed a Basic Electronics Certificate and an Advanced Certificate in Electronics in 1988-91.. So I can understand circuits using the same troubleshooting techniques learned from EM schematics.
Stupid me got into Computers... But then again, my Dad had the foresight to recognize that if the Arcade industry ever dissipated / collapsed, then I'd have something to fall back on..
Ironically, after 18 in the IT industry, I'd love nothing more than to work on pins from a restoration aspect.. Not necessarily repairs.
I even kept my old school notes and texts...
But I'm no electronics guru.. Just the basics..
