[sdiy] Counterfeit chips

[m.bareille at free.fr]

Hello,

Not only CEMs ...

The chineese mafia is still active on Ebay through Mr Hongkongsuperseller , a
big specialist who sale very bad quality parts ( switches , jacks, knobs)  and
fake chips like MN3007, CEMs SSM and many others ... Avoid this seller absolutly
!!! How this guy can be a powerseller is a true mistery to me...

Also take a lot of care when you purchase vintage chips from any 'unofficial'
sources, and specialy if they are at a very attractive cheap price ...

Cheers,

Marc B.
