Hi, just got a old sound system and i'm wondering a couple of questions, mainly to do with wiring.

So, the system contains products from tube technology, the tube amp is http://www.tubetechnology.co.uk/ttunisispowerspec.htm with pre amp http://www.tubetechnology.co.uk/ttprophet.htm

The speakers i have are Sonus Faber, http://www.gumtree.com/p/for-sale/sonus-fa...eakers/90953264 (not me selling them)

Can i plug the preamp to the computer to play music through with this cable, and would it go just in the CD part of the preamp? http://img17.imageshack.us/img17/1241/photo0189a.jpg

i got the two banana plugs as you can see but have no idea where to put em

So how do i wire all this up and what wires am i missing to do so?

and apologies for bad photo quality.

Wiring 101:
computer mini jack stereo out (usually green) -> preamp cinch input (see below)
preamp cinch output (to amp or something like this) -> power amp cinch input
power amp banana jacks (golden, marked right output and left output) -> speakers

Yes.

Any standard line level input. That includes tape, tuner, cd, dvd, aux, ld, video …
Basically in any input that is not phono/mm/mc.
It's impossible to identify the inputs in your pictures, but you should use the cinch inputs. I'm guessing the CD player is plugged in via XLR. I don't know what this is for, if they come as a pair they are balanced inputs. But in your case there's only one XLR input, I can't draw any conclusions from this. Maybe something proprietary, I doubt it's digital balanced.
The block with 10 cinch connectors on the preamp surely is inputs and outputs for various devices, that is where your computer goes. As I said, it doesn't really matter as long it's not phono.
If you need more help you should either take better pictures or list the connector's labels.

edit: I just realized the lower device is the power supply for the preamp.
edit2: cosmetics.

okay what i really need help on now is wiring the speakers to the tube amp, i think i may be missing some stuff.

I was given just 2 banana plugs and that was pretty much it.
as i said i'[m not sure if this, http://imageshack.us/photo/my-images/849/photo0190z.jpg is meant for the speaker cause I'm pretty certain i will need some bare wires to connect them?
This wire though goes into a jack of some sort.
Really confused here help please biggrin.gif

No way. You're wrong on this one. I've encountered this, but only on very very cheap (and poorly built) compact audio systems. As I said, the speaker outputs are the golden banana jacks on the back of your power amp. If you only have two banana plugs, you'll need to get two more. And, as you don't seem to own a speaker cable, you'd need to buy that, too. You should be on the safe side with 2.5-4 mm˛ (AWG 14-12) speaker cable. Don't buy audiophile grade cable, anything of that gauge will work. Every store that has TV's, Hifi and that stuff has it. You connect one side of the speaker cable to the banana plugs, the other side to the speakers (of course). Then you'll plug the banana plugs into your amp*, and that's it.

*Be aware that you have to wire the speakers with the same phase. That means that the +-marked side on your amp should go on both sides into the same color on your speaker. For example if the +-marked right output banana jack is connected to the red terminal of your right speaker, you should do the same on the left side. Which one (red or black) doesn't matter IMHO, some may argue differently here. But thats really sophisticated stuff and doesn't matter much if it does.

According to the picture you linked, those Sonus Faber speakers are set up to be bi-wired. You'll need to somehow address that either by jumping the two sets of terminals or running two speaker cables to each speaker.

Glad to see in answer to your earlier post that the tubes in those electronics are commonly available. Those units are not really an "old sound system"; both are contemporary designs built by an active manufacturer. Yes, some designers still use vacuum tubes!
