Dumb question about the Molex connector (multiple channels)

[thearnicasync]

Hi folks,

I just finished my a12, and I'm waiting for my Avedis opamp. Everything has tested well and I think I only have one last thing: Daisychaining the pre's with the included molex housing and receptacles.

How are you guys doing this? Just cutting the original wires and putting the molex connector between them?

Sorry...totally dumb question!

If you've got a harness with a few extra inches, that's the way to go.
The Molex is much easier to do with the correct crimping tool.

Not a dumb question at all. It's really up to you, but I usually load the chassis from the right side so as to leave some extra wire to work with. For the tidiest job, leave 2 1/2" of wire between crimps, measured from the end of the wire, not the terminal barrel or housing. This leaves just enough slack to maneuver the connector onto the header. If you've loaded the chassis from the left, you'll probably have to splice extra wire into the harness. Solder the splices and insulate them with heat shrink tubing. Whatever you do, don't pull the wires out of the crimp connectors. You can't re-crimp them.

I think I get it...damn, I wish it was in front of me right now!

Again, thanks! I can't wait for the A12...

Actually, I just took two seperate striped leads, spun them together, and soldered them into the molex pins before inserting them into the connector. I assumed I would continue to do this for future modeules, but a tool that makes it easier is of much interest to me. Where can I find one?

Search the web for ht-1919, you should find some places for the crimping tool. I got mine at Fry's Electronics, in Sunnyvale, CA.

This is how I do it. I feel much better with a soldered connection rather than a crimp. I double up the leads even on the last module (and cover the ends with heat shrink tubing) so that when I add another in the future, it's ready to be soldered into the new Molex connector.

It would be great if someone could post pictures of the different techniques used to wire up the harness

Shane has some nice photos of his work up at The Lab, http://www.prodigy-pro.com/forum/viewtopic.php?t=2883. Good work Shane!

We'll finally have photos up next week or so, in the CH01 instructions.

Thanks Tim,

I feel guilty posting pictures of my work since it is you who is responsible for the fantastic design. These modules would certainly make attaractive (albeit expensive) holiday ornaments! It is indeed a shame to have to cover them up. Perhaps I'll deisign a new front panel with lucite so we can all see the work inside.

At any rate, anyone out there trying to decide if they can build one of these, I recommend a simple electronics kit (function generator, paia, etc.) first, but don't be fooled. If you can build a model airplane or model car you can build these. Just read the directions until you know them, and take it one step at a time. The reward will be great!
