frank - yea its a 7660s. this was the first layout i made so it's not the neatest. i'll redo it in the am, i'm a little too out of it at 3am my time to it right. i just used a 12V power supply from radioshack i had laying around, i'll have to check what i gave my buddy and get back to you, but i think 1amp should be fine. it cost me like maybe $15 to put it all together including the enclosure. if you figure an enclosure it $5, the chip is like $0.50 max, the regulators are like $5, plus the wire and odds and ends.
iggy - what documentation do you mean? this way i make sure when i redo the layout i don't miss anything. also the grounds are all connected between each jack, and a one jack is also connected to the board at ground. the 7809 is a power regulator, if you look on ebay or tayda for L7809 and you'll find them, also frank posted a link to ebay for them from tayda.
you just have to remember that there is a heatsink on top of the regulator,
hopefully induction doesn't mind, but he helped me design this and is similar to one he has made, look below to see the wiring and how to handle the heatsink look at what he has done. the only difference in the one i built is that i used all the same jacks, but for mine i'm going to change it and do what he did.
here's what induction said he did for the heatsink:
"Finally, notice that each regulator has a heat sink made of three small washers. The washer size was selected for maximum contact with the regulator tab, and there is thermal compound at each mating surface. The tab of each regulator is shorted to the ground leg, so I heat-shrinked each of the regulators as a precaution against accidental shorts."
better to hear it from the person who taught me, then me try to explain it and make a mess of it all. lol
