Connecting a soundbar to a tv?

Me and my family recently purchased an Auvio soundbar from radioshack. It came with an RCA cable to hook up to our TV. However, my TV uses an "S/PDIF" jack for audio. I don't know where to get one of these, but it's been really inconvenient having to switch the RCAs to whatever component I'm using at the time instead of just hooking it up to the TV. What should I do?

Multimeter DIY Repair?

I have a Radio Shack digital multimeter, Model 22-174. Since the 10 Amp measurement circuit is not fused I blew this circuit and that part of the meter does not work now. I like this meter and would like to know if I can DIY repair it and what I need to do. I have looked around the Internet and have not found any information including the Radio Shack site. Was looking for the wiring diagram only found a parts list. I hope that I can fix it. If I can fix it I will fuse the test leads (black lead) or work out an internal fuse for this circuit so I don't repeat my mistake. Any help would be nice. Thank you.

Should all grounds go to the same negative bus on a breadboard? Answered

Whenever I see circuit diagrams they just show a ground off some components. When I'm designing on a breadboard should all of these go to the same negative bus on my breadboard in order to function properly? I've got one positive and one negative on each side (standard 6" Radio Shack model). Also, I would assume that a series circuit would be for those instances when you have no negative bus at all and need to ground back into the power supply as well? Thanks!
