Juli@ @3,3v

Today i accidentally put 3,3v on the 5v-point of the Juli@ and it worked. I use only the digital part.
The 5v 'fingers' of the card are broken to disconnect the mobo-5v. 5v is suplplied by a linear psu. The regulator is capped before and after (capped 5v-grnd and 3,3v-grnd).
Today i used this psu to charge a LiFePo4, so it was set to 3,6v to do so. Later on i reconnected the Juli@, and forgot to set the psu back to 5v. Juli@ worked! Then i connected the LifePo4 to the 5v-point of the Juli@ and it sounded better than with psu.
I checked the datasheets of the digital chips, and they all work within the range of 3,0 - 5,5v.
Next step will be desoldering the regulator and feed 3,3v to both 5v and 3,3v holes on the Juli@-board.

Still, could somebody try this tweak and report, because i'm not shure i did right. If it works right, we could save one supply on the digital part of Juli@.
