Thanks mate. Very informative post. I never realised the smaller electronic devices runs off DC.
No wonder you were confused with my earlier post...

So does it make sense to say then... AC is used on the Z 80 not because AC (as such) "makes better flavor" than DC...?
Rather because the frequency can be adjusted with AC, the flavor can theoretically be manipulated.
I really do taste a difference between lower and higher frequencies....not so much the flavor, but the heat and "intensity"....which I would think relates to flavor....

That makes sense to you?
