Very understandable. Not all manufacturers will go to the trouble and cost of producing user engineering schematics and maintenance manuals. In fact very few do. ATC have sent me specific circuit diagrams and board layouts (two separate pieces of info about the same circuit board) in the past. ATC don’t have a problem with this because they are an engineering driven outfit that expects and anticipates that professional users will need to sometimes make onsite repairs on damaged gear (misuse being a common occurrence in a professional facility that is leased by various producers and musicians regularly).
The cost of proper professional documentation (engineering diagrams) and revision tracking is not surprisingly very costly and it is often hard to justify in a boutique market. In a boutique market, personal notes and hand written schematics are more than sufficient for a small manufacturer to produce great quality gear. Unfortunately this is not suitable fir dissemination to repair technicians....
