[Amps] Direct rectification of AC mains to drive the amp, VDD Supply

[Manfred Mornhinweg]

Alex,

I fully agree with you on this. I most often do it that way too. Even 
without the benefit of a rubber mat. But in this crazy world, where some 
people who mess up and hurt themselves look for other people to blame it 
on, and often succeed in their claims, one has to be careful when 
recommending any methods that aren't 100% dummy-safe! You never now what 
subspecies of homo not-very-sapiens might read it, understand only half 
of it, and then try to apply it!
