I think that the sound amps run on 17v, so you will need to wire in the black transformer at the top right of the picture.

I can't tell where they lead, but I assume that it leads straight to the 110v mains supply? Anyway, that needs to be used to power the amp in some way.

Ok. The system should be here tomorrow. That is the pic the guy who sold it to me sent me. I'll be able to take better pics tomorrow (or Sat., depending on when it gets here). Thanks for all the help so far.

I think what Grant is looking at, at the bottom right of the picture, is a 3-pin connector which feeds AC to the PSU & Amp transformer.

yes,i think if it is what i think it is then i would install a euro type socket on those wires and then have a standard machine lead which can be unplugged

Ok, here are some pics of the wire you guys were asking about. Basically, the wire is coming from the transformer. It apparently has another wire from the transformer that plugs into the back of the power supply, so I'm assuming that the transformer is where the power goes through.

So all I have to do is cut the end of the wire off (that weird looking connector) and just splice in a socket that's a three prong right? Just strip the wires a bit and then connect to a longer wire that is connected to a three prong socket?

well sort of yeah,if you want to do a professional job then you would get a standard machine lead,like this

and install this in place of your existing plug

then you have a system that can be unplugged and has an inline filter
