George suggestion of getting a make and model will be the best way to ascertain the details through some research, probably easily done on the net. However if the equipment is old or stightly unusual then you may need the guidance below. It would be important here to get some eyes on the equipment itself. I am assuming this is a peice of kit that had a wall wart type adaptor. If so you should see if a DC or AC input voltage is mentioned either near the input socket or on a plate elsewhere on said kit this should tell you what type of voltage, how much and possible maximum current draw. It is vitally inportant you ascertain whether the input is AC or DC here, if you plug a DC current into an input that accepts AC then you are likely to cause internal damage. Voltage is also important, too much will potentially cause damage to some equpment. If the unit is DC powered then there are usually plenty of multi-voltage power adaptors that come with a number of DC jack plugs to accomodate your kit. My guess is that if it takes batteries your input is going to be of a fairly standard DC type ranging from 4.5 to possibly 12 volt. You could take said device along with you to somewhere like Maplin, they may very well be able to help you there. Regards.

Sadly, the broken unit has been chucked and I didn't have an opportunity to record its particulars. Is it possible to deduce from the battery power required what I should be looking for in terms of voltage output etc? And what might be the other things I need to ensure are compatible? With thanks.
