OK, maybe the bet was a bit one sided, as most SM PSU's are made in China and THEY produce EMI not the analogue ones.
How can the purchaser be responsible? They don't design and manufacture the item ! EMC rules on these PSU's are very clear. If however, the manufacturer chooses to omit vital EMI suppression components because of commercial imperative, then they are breaking the law. Quality control does not enter into the equation, neither does marketing. The government organisations, who originally demanded that test methods and limits were put in place as part of the overall CE scheme, and now do nothing to enforce the law are equally to blame.
