You should be ok using a 9V DC adapter (or even a 12VDC for that matter...
The AC is rectified (converted to DC) inside the unit anyway.
Sending DC will not be a problem as it will pass right through the rectifiers.
You do not even have to worry about polarity.

I was told to be especially, especially careful about ensuring that polarity is correct. Otherwise "meltdown" could occur.

Sometimes people on here poke fun at newbies (which I definitely am when it comes to electronics), or give wrong advice as a bit of "hazing" -- just want to be sure this is not the case here since we are talking about something that could be dangerous to my family.

Thanks,

- How would you determine the polarity if an AC voltage? - Tweekeng 16:09:27 08/27/07 (0)
  Answer, you can't since an AC voltage is constantly changing polarity.
  No matter what way you hook DC up to the AC input the DC will be "routed" through the diodes and the unit will not know the difference.
