I went to radio shack and got the relay I needed. I then built a box that will pass 10A to several RCA connectors (I wanted to be able to plug the units plugged into the box into the K3 when portable with a sub set of my goodies). Anyway I then also got a few of the cheapy cores that Radio Shack has there. I put an LC filter on each port just for fun... I figured if I was making it it only takes a short bit of time to put some RF filtering on each port... I also stuck a couple big bulk caps in there just for grins. Then an LED to signify that its on too (why not...). Finally installed a suitable cord with an APP on it to supply the 10A of power. All in all its a useful little box and every piece of it can be had at Radio Shack still today.
