Hi, I'm Steve from NZ. I stumbled across this site after watching a few topics on Youtube...BTW one of the better channels.
I'm originally Post office trained, used to maintain electromechanical telephone exchanges (strowger) back in the '70s, retrained on crossbar, retrained on NEAX61, retrained on PABX, pretty much all the early electronic ones before deregulation, repaired circuit boards for them, got into TV, VCR, CD, phones,microwave ovens, pretty much everything old tech. Had my own repair shop for 10 years, it's all throw away now I'm doing more on cars than anything else........kids....cars....electronics......fail.
Working with any sort of technology, you've got to retrain every single day.
