RE: 9 V AC

["Scott Wilson" <swilson@scratchstudio.net>]

Well, give the 9V dc ones a shot. it's got to end up DC eventually, 
and the ART boxes may have just had the rectifiers/regulators in 
the box instead of the wart. 

As far as amperage, that won't fry the box... incorrect voltage will.
If a power supply says that it's 9V 500mA, that means that it can
supply 9V at any current draw up to 500mA. So even if the ART box
only took 350mA, then that's all it will draw. If it took 900mA,
however, then the wall wart couldn't supply the whole 9V, and it
just wouldn't turn on, or if you left it on, then the x-former might
get too hot, but nothing immediate.

The thing to watch out for is using the wrong voltage... But of
course, this is all theory... don't blow yourself up, and if you
do, then don't blame the author of this email! :)
