You can buy a multiple voltage AC adapter (battery eliminator). They
usually start at 3-V and go up to 9-V or 12-V. It has a switch to select
the voltage. It will power most solid state radios that use less than
1000-ma (1-amp) of current. Radio Shack has them.


The kind of radios he's talking about are the old tube farm radios that ran
on anything from a 6 volt tractor battery to 32 volts or even a battery bank
with 90/22.5/9 volts like the old tube portables.
