I am considering buying a DX-440 off someone for $40. It requires

wondering whether this should put me off the purchase because it
may have shortened the life of the radio.

If the radio works fine and you like it, buy it. Normal variations on
the AC line (115 to 125 volts) can cause a few tenths of a volt
variation in the output voltage even on the factory adapter.

Also, you say you have "a correct 9V adapter". If it was *specifically*
made for the radio, that's great. If not, make sure the voltage AND
*polarity* are correct for the radio.
