I watch his video's regular, I can feel his frustration about former failed repairs but, hey, if I can fix it, it feels extra great
I'm in the repair business too, it can cost a lot of energy / concentration and there is the risk of screwing things up, getting things ready on time, etc. For most in his business. So I think he needs this to get the frustration/stress out of his system.
What he does is far from what I do, that is why I like to see it. I could never do what he does. I get (industrial) measurement and calibration gear from all kinds of brands and types, most are without service manuals or schematics and almost every repair is a first. Many instruments are more or less unknown to google. I need to work very clean and often after I'm ready all flux remains are gone. I'm used to work on instruments that are very clean on the inside. I use a good flux but not by far in that amounts. I have an arsenal of cleaning products. I have an ultrasonic cleaner but I do not clean pcbs in it.
I'm not a wicker, I have some, but I'm very handy in using my pace desolder-iron. (but it starts to wear out). I can not remember the last time I removed a solder-pad or trace.
I admire him because I think his consumers and their electronics would drive me crazy. Dirty, cheap made expenIsive junk and frustrated owners.
Most of my customers are more or less techs them selves. That makes it more easy to talk to, they appreciate what I do and know it takes time. I have my lab here at home, no personal, no rent, no travelling, no expensive stock, all the technical
toys tools I like (so not what the boss likes) and interesting work, so I'm happy.
Not all repair men are the same. I think you probably have to be a bit coco to like and do this work.
