I need to buy a couple of dc power adapter thingies to power a couple of stompboxes off the mains instead of using batteries. I have the DC mains adapter but what on earth is the correct name for the little plug thing I need to buy to solder onto the pcb that you plug the mains into?

From what I can discern from the Digi-Key catalog, it's a DC power jack. Not sure what they call them over there...
This is really a ChrisK type of question...I found some Digi-Reel DC power jacks on page 456 of the US Digi-Key catalog...but as far as what model/style...or which one is ideal for your application I will have to plead ignorance...

In the U.S. that is called a jack, usually denoted as Jx. The thing that plugs into it is called, er, a plug, usually denoted as Px.
Sometimes jacks are called sockets, but only most rarely. Now, an IP software connection in a PC is called a socket......
Maplins search confirms a jack is the male part of a plug.
Over here, a Jack may be the male name of a plug......
Measure the outside barrel diameter of the plug. It looks like it's aboot 5,5 mm. You also need to know the diameter of the centre terminal in the socket, which may be 2,1 mm or 2,5 mm. These are the two different centre terminal diameters common in the U.S.
A digital caliper is real handy here. If you can't discern the centre diameter, buy some of each (it's cheaper than paying shipping twice). Definitely buy at least one 2,1 mm plug and one 2,5 mm jack/socket as reference gauges. Mark them so.
In the future, if it fits into a jack/socket, it's a 2,1 mm jack/socket, and if it does not fit, it's a 2,5 mm jack/socket (don't force it, or you'll re-gauge your gauge). (These are not to be confused with a jack/plug. )
by the way: from my limited experience, digikey send all their goodies from the States - even if you use use the UK version of the site/catalog. This incurs a pricey delivery charge unless you've spent more the £50.
For something like this, you're almost certainly going to be cheaper going to Maplin.
(on the upside, I was also sent a copy of digikey's catalog. A hefty, hefty tome. In many ways it's better than the website if you're not quite sure what you're looking for. It's got a lot of mouth-watering gear in it - I didn't know you could get some of this stuff. It's the closest thing I've seen to geek porn!)
don't get me wrong - digikey seem pretty good. They were happy for me to change part of my order, despite it being ordered in specially.
that's an interesting take on the derivation of "loo" though. I'd heard it was after Louis- a French king the English held in particularly low regard. I think it was in this documentary, , though I may be wrong...
