Interview with Electronic Repairer Mr David K.T.TU

Mr David is a gentle and humble man. When i approaced him to ask whether i could interview him about his electronic repair business, his response was "Sure anytime". He has no problem showing me all his repair stuff like his own technical books, test equipment, schematics and etc. 15 years back he had trained many students in his repair shop and even till now some of his students still come back and look for him to have a chat and talked about electronics.
