Times are changing me auld china (clue) - leaving a circuit diagram in
the products is an invitation to get your gear cloned, these days......

I've seen that excuse given on various occasions. However the reality is
that a skilled engineer can take a set apart and work out the circuit. It
takes more time, skill, and effort than having a set of drawings. But if
the copy doing the 'cloning' are determined it is easy enough.


Sure.



I fear that the real reasons for refusing to issue diagrams and a decent
service manual are more often:

1) Sheer 'canna-be-bothered'


No doubt!



2) Fear that it will show the circuit is less impressive than the hype.
Don't want to put off the flights of fancy in reviews or shops. :-)

3) Too dim to realise what I point out above. Or know the circuit isn't
worth anyone else cloning. :-)

4) Trying to control the service and repair market. The idea being that
the
company makes more cash from either doing all service itself, or by
charging 'appointed agents'. i.e. anti-competitive practices. Probably
illegal, but hard to deal with.



I would be tempted to query that, given how little stuff is really worth
repairing these days!





Slainte,

Jim
