Advent 300

I have just received one of these amps but it is missing the wire connectors (jumpers?) in the back which allow it to run as a power amp as opposed to a preamp? I honestly don't even know what they are called. Any help? Thanks.
you can buy a new pair easily here on A'Gon or elsewhere on the web.
All you have to do is put a pair of interconnects between the amp out and preamp in. I have a 300 and thats what I use.
I meant pre out amp in.
Thanks guys. I was hoping it was that easy.
