DIY Eichman bullet RCA plugs

tom1356 · 15th March 2003, 01:51 AM

I made a set of these today using scrap oak and .9999 silver wire. They came out really nice ( way better than they look in the pictures) but I havn't had a chance to hear them yet. It took about 20 mins to make the two of them. I will do them over again real pretty now that I see they work.

See the originals here.

You should probably call those "DIY 47 Labs" rather than "DIY Eichmans", because the Eichmans themselves appear to be knockoffs of the 47 Labs Otakit RCA cables.

What a great idea! I've been using the originals (copper) for a while and really like them a lot but there is no reason yours wouldn't be better. How is the center pin made?

cheers

Link to the Otakit:

http://www.47labs.co.jp/4708.html

47 Labs utilizes the conductors of the cable for the conductive part of their two-part RCA connector. The 47 Labs Otakit is a natural for solid-core cable, and sounds substantially better than the Eichman.

I was not aware of the 47 labs connector.
Now that I've seen it, I will try to copy that.

The center pin is just a silver wire, bent at the back to keep it snug and bent slightly at the front to make contact at only one point.

I will also try to remove some of the contact area on the return wire to resemble the eichman a little closer.

I'm really kicking myself for not doing this earlier.

Version 2.0
It's like a hybrid between the 47 labs and the Eichmann. I am working on doing away with the center pin but I'm not quite there yet. It sounds really nice. At first listen a layer of glare on the letters S, F, and T has been removed. Doing one at a time and listening made me want to do the other one right away.

Hi,

Nice work.
If you like what you're hearing, here's a source for even more inspiration:

AUDIO CONSULTING

Personally I had good results with stripping/skinning caps, you may want to try that too.

Cheers,
