Given how cheap a 9VAC wall-mount transformer I, why would it not be better than a 5VDC-9VDC convertor? Also the 5v supply would need to handle an addition 1.25 Amps at a guess, what is the 5V supply in this case? Typically circuits that use a sign wave are concerned with the zero-crossing point and not so much the peak or what the shape is near the peak. Not saying all uses do this, it is just my experience to-date. -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com] On Behalf Of firstname.lastname@example.org Sent: Monday, September 16, 2013 4:57 PM To: email@example.com Subject: Re: 9VAC from 5VDC?

And if there is one that wants to use the AC frequency - it implies immediately that the accuracy is not the top priority there. I am more concerned about some potential influence like unwanted noises/hums, etc in analogue add-ons. (modems? audio add-ons?) -- SD!
