Other numbers to consider:

ORIGINAL HARDWA
Input 120 VAC 60Hz 50W
Output 13.5VDC 2.5A

POSSIBLE REPLACEMENT
Input 120V AC 60Hz 23W
Output 12VDC 1000mA

Your 'possible replacement' doesn't provide as much power. The voltage is
not an issue (if you measured the original one when it was working, it was
probably between 10 - 18 volts, "wall wart" transformers are usually way
off), but the amperage probably will be. The original one put out 2.5 amps,
the replacement puts out 1 amp (1000 mA). At low volume it may work fine,
but when you crank it up, the replacement power supply will not be able to
provide the amount of juice needed.
