I have got a lead, S video at one end and two phono connectors at the other....?

Question

can I connect my laptop directly to an amp with this cable?

Answer 1

The s-video only carries pictures - no sound.

You need a cable that plugs into your 3.5mm headphone socket in your laptop and splits into the audio (red & white) cables into your amp.  Most electronic shops should sell it (Maplins etc) else buy it very cheap online.

Answer 2

no

Answer 3

From the sound of it, no. S video splits out to 2 streams (Chroma and Luma) as opposed to the single stream of a composite cable or the 4 streams of a component cable (RGB and sync)

The cable you have will just carry video signals. 1/4 inch jack to 2 phono's is the one you want, run it out of the headphone socket.
