As many of you know, I am very willing to post advice on repair and maintenance. However, recently there was an example of someone taking part (not all) of my advice and messing up his instrument. I do feel very sorry for this, although part of what he described happens sometimes during the course of repair by a competent technician. Surgeons do not offer step by step instruction for routine operations, because they are aware that all sorts of complications can happen. To be absolutely clear, the member involved has NOT sent me any message of blame or disappointment. Should I refrain from giving repair advice? Should I always include a disclaimer? Or should I let people go ahead by themselves without advice? I am very interested to hear your comments.
