Internal wiring

[bumpy]

I am planning to unite the 'contents' of a power supply box and a valve amplifier box into a single box so there will be some need to renew/extend the internal wiring.

What wire do I use and because of the need for a number of colours where can I buy a handy package of perhaps 3m lengths of a variety of colours?

Never thought to look under automotive wires. :) Is it normal to use solid core or multi strand in an amplifier?

Good, but shorter lengths would be better as I only plan to do this one job.

Think either would do. Maybe pop into maplins or look online. They used to do cabling

Will any of these wires be carrying B+?

Be mindful of voltages, and ensure it's suitable for the task.

I'd use good quality mains two core + earth solid core cable. Just strip out the black wire and mark each end with a short bit of sleeving to colour code. Packs of short length multi-coloured heat shrink sleeving are available. Cheap solution. Buy in B&Q.

Good tip, I have lots of mains lighting cable and shrink wrap stuff.

I will pop in next time I'm near :)

There you go. Sorted, cheap.

I did one of my old Leak Stereo 20 amps with that years ago.

I see that PVC covered wire is much cheaper than PTFE. Is there a sonic difference?

Probably not. PTFE is regarded as a better (and more fashionable) dielectric (insulator), but personally, I reckon it makes bugger all difference.

Where do you stand on silver wiring :)

Where do you stand on silver wiring :)

Generally, I prefer pure copper. I don't like plated copper, but I do have pure silver leads that sound rather good. Very revealing though.

[CornishPasty]

I'd agree with that. I find that silver plating does something to the sound which isn't there with pure copper. There's nothing wrong with pure silver either. Rather than say silver gives a sharper sound I'd prefer to say that copper sounds slightly warmer. Dare I say that in some systems you'd be hard pressed to tell the difference anyway.

Hi-Fi Collective also sell the kind of stranded copper cable you need.

Thank you good people. Lots of info there.

Well have fun with the project and let us know how it goes. :)
