That's what I thought. What am I missing? An expensive power cord?Apparently what you're missing is an expensive earth ground rod, Rod. :)
Every component has a transformer to convert to DC.
Except those that don't. :)
And of course it's not the transformer that converts to DC but rather the rectifier. And that really just gives you pulsed DC. Add some filter capacitance and you get DC with sawtooth ripples riding on it. 'Course you can add voltage regulation to reduce the ripples, but by that time I've completely lost interest in AC power supplies.
I suppose SETs with AC heaters could be the exception which is something else, I don't understand.
Seems to be a matter of personal taste/preference.
Did he ever get it?
Not yet. I've since given up.
Suffice to say that in Henry Ott's definitive "Noise Reduction Techniques in Electronic Systems," chapter three's 43 pages on grounding has ABSOLYTELY NOTHING to say about actual earth ground being anything special or that tying your local reference grounds to an actual earth ground will reduce noise in the system.
Zip. Zilch. Zero.
