Default Umbilical cord suggestions

Hi all,

I've been working my way towards putting my breadboard IGC into a final design enclosure (pics soon) and would like to ask for some suggestions on the Umbilical cord between supply and amp.

I will have two power supply housings and one amp box containing both channels. I only need about 1 foot max cord length for each. Envisioning the cords being fixed at supplies with connectors on amp for easy moving.

1. Wire suggestions? Braided seems logical so I'm not worrying about stressing and breaking a solid cable.

2. Connector suggestions? Type and and source would be great!

Anyone using plain 'ol Home Depot appliance/tool replacement cord with the three wires? I'm also very open to wire suggestions from places like Parts ConneXion as well.

Thanks in adavnce,

Steve

A practical choice is Kimber Speaker cable (8 wires) and CB radio mike connectors (available from Electrosonic).

Later I found that this cable sounds a bit flat and laid back and changed for Cardas 20ga. hookup wire. Although more expensive, it's worth the upgarde.

Do something really well. See how much time it takes. It might be a product, a work of art, who knows? Then give it away cheaply, just because you feel that it should not cost so much, even if it took a lot of time and expensive materials to make it. - JC

As for connectors, I've seen a lot of people use these; (from parts express)
090-535 CB MIC PLUG 4 PIN FEMALE $1.65
090-542 CB MIC CHASSIS MOUNT JACK 4 PIN H $2.50

And it's what I've gotten for my first IGC too.

As for wire, I found some nice 16ga 4-wire stuff at Home depot, and it's cheap, cost me $1.20 for 5 ft of it. I'll have 2 grounds and then +/- 25V. Of course mine isn't done yet either, but it's the best I was able to put together based on what Ive seen here. I know others have used a bunch of single wires, and then sleeved it but that seems like just a bit to much work.

The neutrik speakon connectors are great, and you
can get them in 2,4, and 8 pin connectors.

www.partsexpress.com

and they're cheap! compared to XLR's etc.

ah yes those speakons are pretty good (and not too expensive) but they're pretty big too. And, most important, not meant for power connections. The Neutrik Powercons are meant for power connections and (thus?) are much more expensive.

Oh well, methinks speakons are good enough for a GC anyways.

Speakons are fine for the power connection from psu to amp, they are well within their operating limits there.
