I suspect this is heading way deep into proprietary business issues. Since C-J acquired McCormack, it would seem that any notifications about the equipment would be the responsibility of C-J and likewise any sharing of equipment schematics would be their prerogative.
You would expect that this was the case but there is a thread on Audioasylum with a 2009 date on it where Steve Mc. himself responded on a thread telling a user that PDF schematics were available and he normally responds immediately to email requests for them. That date was about 10yrs after CJ bought the rights to the DNA amps, so if a legal limitation was in effect then the last thing he would be doing is posting and publicly offering schematics to the amps on audio forums. There are also other threads on alternate forums with later dates where people supposedly emailed him and received the schematics. Suddenly in the last few years this openness is no longer the case. I should add that I did ultimately find the schematics by contacting users on DIYAUDIO, but it shouldn’t have to come to that for a 30yr old electronics design. They should be public info after a certain period of time.
My suggestion of safety was not due to your prior statement. I understood your intent. I was just covering the "safety" aspect in case that was the motivational factor for SMc.
