Yep Nino, This would be purely educational thread, nothing to do with tips & mods covered in the other Technical threads.
The way i see it :
"Hints & Tips" - Aimed at specific machine problems e.g. "how to repair/mod Star Wars machine" etc.
"General Repair Procedures" - "How To" repair a generic items on most pins, such as rebuild a flipper kit or pop-bumper etc.
"Technical Training" (new) - Explains how electronics/component work inside a pin, plus fault diagnosis etc.
