I don't have any cool equipment to show off. I'm just trying to throw together something and I'm looking for advice because I have no idea what I'm doing.

I have an Onkyo TX-SR507 AV Receiver. 5 speakers and a subwoofer hooked up and it sounds pretty killer in the small space it's hooked up.

I want to go to 7.1, and the manual shows how to add 2 more speakers into the mix by going through a power amp.

I have an old Technics SU-V98 Integrated amp. Can I use this, or are power amps and integrated amps two totally different animals?

Thanks for any help.

It has those, but I'm not figuring out where to plug what.

I pulled those out and tried running rca cables to it. No sound.

When I leave those staple things in and run a cd player to the technics, it plays and sounds good through the 2 speakers plugged into it.

My problem is when I pull out those staples and start trying to hook it up to get the onkyo involved and get those 2 speakers to play what the other 5.1 speakers are playing.

Lost.

Thanks for the guidance. I'm all over this as soon as I get home from work tomorrow.

Hooked it up and nothing.

So I went and pulled the rca jacks out of the back of the onkyo and holy crap (I forgot to power it and the Technics off first) when those male ends of the rca jacks accidentally touched each other, I got crazy loud noise coming from the 2 speakers hooked up to the Technics.

So now I'm thinking/realizing the pre out jacks on the onkyo are not red and white. Does this mean I'm using the wrong cables? I was just sticking white on top and red on the bottom, as that's how all the jacks are colored all the way down the line. Is there another type of cable?

Found this at the curb today. AKAI GX-747 dbx.

Powers on. Standby Direction seems to be stuck on. The tension arms move back and forth. Clueless.

Dropping this of at my Father-in-law's. He seems pretty stoked.

After describing what it's doing after I powered it on, he actually passed on it. Looks like I'll try and fix it.

I'm being told I need to do this...

I've got everything except for the belts. Gotta make sure I find the exact ones I should use.

Will do. My Father-in-law has tapes. He's got at least 10 reel to reel machines. 10,000+ records. Out of control.
