Hi

Its just a twisted pair cat5 cable. What would you suggest? The reason why I choose this, apart from having a pile of it, was that Dave (Planet10) suggests using a single pair for the speakers cables.

Very nice, Richard. I like the cleanness of it. Looks like everything bolts directly to the heatsinks. have you any shots with the cover off?

Never mind Odd, the cover-off shot didn't render on the first view. Oh well.

That is one beautiful amp, congratulations.

I found your amp very interesting because I was planning my build to be very similar, although with Peter Daniels boards.

I must say, I would not normally speak up, but I must agree with jleaman - that cat5 output wire has gots to go!
As for a suggestion, I would say 18 or 16-guage. I am going to be using regular old stranded copper 16g.

Once again, hurrah on another F5 added to the world, I sure wish I could get mine done!

You really need to use speaker cable for the output, or at least something much thicker. I don't think cat5 will handle any significant current (2A at a guess).
You are also increasing the output impedance of the amp.
If the insulation melts, then you are going to short the amp (because of the twisted pair).

I'll get to it right away! Thanks for the advice guys.

Hi

I have some DHLABS silver plated hook-up wire. It has a diameter of around 1.5mm

Click the image to open in full size.

Will this be OK?

I just did a quick google search; 1.5 mm is about .05 inches which is about 16 gauge which is about about 13 amps. Should be plenty.

There are a lot of web sites out there that give wire diameter and current limits. Here is one: Xtronics Wiki.
