Question about assembling my own DIY AC Cable

@carlsbad  said:

Put the red cable and black cable in the hot pins and the green to the neutral.  The connectors are probably marked.  

Me thinks you need to reconsider your thinking...

I would terminate the black banded conductors on the neutral pin terminal of the male plug, the red banded conductors on the Hot pin terminal, and the green banded conductors on the ground pin terminal. I would only connect the shield drain wire to the ground terminal on the male plug. Float the drain wire on the female IEC connector end...

@mitch2 and @erik_squires ,

You beat me to it...

@rayleigh ,

Looking at the specs of the IEC connector:

Conductor: Pure Copper

Pure copper is a soft metal and does not have any memory retention properties. Copper contacts of the IEC will not hold the female contacts tightly against the IEC inlet male plug blades... A poor connection can causes micro arcing and cause harmonic distortion. I would look for a better IEC connector.

What wire gauge equivalent is the Hot and neutral conductors?

The individual insulated conductors look like solid core silver plated copper wire. Yes? That’s good...

What piece of equipment will the cord be connected to? Analog? Digital?

I will connect it to my tube amp here is a picture of it

FWIW, my tube ARC amps don't like shielded power cords.

I disagree, all audiophile IEC’s even from Furutech or Oyaide have the conductors of pure copper.

Are you sure about that? All female IEC connector contacts are made of pure copper? I see the Furutech says pure copper but I would bet the copper has some sort of a alloy that gives it memory tension.

Furutech top line grounding type 125V duplex receptacles use copper contacts but you will notice Furutech uses a non ferrous stainless steel spring clip for its’ memory tension to maintain a tight solid fit connection against the male plug blades.

Here is what Oyaide uses on the C-004 female IEC connector. Beryllium provides the memory tension.

The basic material for the Oyaide C-004 is Beryllium Copper, which provides maximum conductivity, strength, and a secure contact.

I have an AudioQuest 125V duplex outlet that also uses Beryllium Copper for its’ contacts.

I would suggest you check with a credible source if the IEC connector you are looking at is just pure copper.... Pure copper alone is soft copper.

Do your tube amps not like shielded cables terminated on both ends (may cause ground loop) or were you saying that there is a problem if they are grounded only on one end?

For a better word a shielded power cord sucks the air out of the music.

As for grounds loops..., I must be blessed I have never experienced ground loop hum from any audio equipment I have ever owned.
