Sam,
I agree with Bob. Don't take 4.5V power supply, find 5V one instead. I
would also avoid using power supply with interchangeable plugs or
switchable voltage...
Take a look at this one, it should work:
http://www.ebay.co.uk/itm/UK-AC-Wall-110-240V-To-DC-5V-2A-Power-Supply-Charger-Adapter-Plug-/290770066033?pt=UK_Sound_Vision_Other&hash=item43b33f1a71
Regarding the plug, the jack on the board will fit connectors with 5.5
mm - 6 mm outside diameter and 2 mm - 2.5 mm inside diameter. Another
important thing about the plug - it should have (+) terminal inside
and (-) outside. While this is a more common arrangement, it is not
unusual to have the opposite arrangement as well.
An available source of 5V supplies is USB chargers. Just replace the
USB plug with the cylindrical DC one...
Thanks,
Sergey
