Another strategy is to make some PP9 to PP3 adaptor leads by soldering on PP9 snaps to a PP3 lead. RS sell the PP9 snaps (464-754) - they look a little modern, but are better than nothing and are fine for an adaptor lead... Plus, I have made up some leads with 4mm plugs on one end, these battery snaps on the other, which plug into my bench power supply and connect straight onto the radios battery snaps.
And another thing (I'll shut up in a minute - honest :s) - you can take apart dead PP9s and put a PP3 inside, or get a battery holder that will take 6 AAs that will fit into the box. The modern plastic cased PP9s are best for this. That said, a 4Ah PP9 will probably last longer - AA cells average typically half that...
