Hi Wombat
Yes its pretty common for the older or cheaper power adapters to measure higher than the label. Under their rated load, they would be close to their rated voltage, but for something that uses little power like the Maximite, the voltage is just too high.
The Maximites 5v regulator needs to dissipate the extra voltage as heat, and anything over 10 volts is just too much.
If the #3220 regualtor is providing a true 9v, then it will fix your overheating problem. Or you may find a old 6v adapter that measures at like 7 to 10 volts, it would be OK too.
