..these usually states the low voltage ampereage and voltage too, like
in "Input 230VAC ~ 50 Hz 20W, Output 13V =-=-= 1A 13VA ", or 
"Input 230VAC ~ 50 Hz 75mW, Output 9VAC ~ 800mA 7.2VA", no?

..on replaceing the transformer adapter, you basically need to match the
modems power demand, it should be printed in the docs or on the case.

..the only showstoppers I can think of, is noise filters set to weed out
50Hz in the US and 60Hz elsewhere, and clock circuitry useing the
power mains as a time source (hellooo!).  ;-)
