I am considering buying a DX-440 off someone for $40. It requires
a 9V 300mA AC adapter. The one with it is a 9.6V AC adapter. The
radio seems to work fine. I have a correct 9V adapter, but I was
wondering whether this should put me off the purchase because it
may have shortened the life of the radio.

If the voltage is AC and not DC on the transformer I wouldn't buy the
radio. Otherwise 9.6 volts DC is well within the tolerance of the radios
voltage. Voltage should be no more then 10% above or below the required
voltage.
9V * .10 = 0.9 volts so the range of the radio input voltage is from 8.1
to 9.9 volts DC.
