RCA making supplies?

Post by Bob257 » 24 Nov 2019 21:50

Where can I find the material to attempt my own RCA cables? Wire, ends, silver solder etc.

Order Belden 89259 cable from Blue Jeans cable:

https://www.bluejeanscable.com/store/sh ... /89259.htm

Get Switchcraft gold connectors from Markertek:

You can spend more on cable and connectors but don't think you will do better.

Right angle switchcraft are good if you have a tight space to fit the cable:

I can recommend a DIY kit from Douglas Connection here: https://douglasconnection.com/products/ ... ct-cables/ Choose Alpha or Bravo depending on your budget. In addition to cable and RCA plugs, the kit includes Cardas silver solder and heat shrink tubing. Doug is great to deal with. Instructions are included, and you can email him directly with any questions. Of course you shop a la carte as well and pick higher quality cable and plugs if you want.

I like the Neutrik/Rean RCA plugs and sockets - excellent quality without exorbitant price.
There are lots of cable options, Blue Jeans (Belden) is well-regarded by many while others think there are better cable options.

A good source for Neutrik Rean RCA connectors, as well as Cardas cable, is kabusa.com. (I use Neutrik Rean connectors and Mogami W2528 cable quite satisfactorily.)

I've been making cables for well over four decades for both residential and commercial installation purposes. Your question requires research to make educated choices. Read up on cable mechanics before selecting your preferred wire. Specifically, study manufacturer's data regarding strands, shield types, jacket materials and flexibility. Cables for consumer use and fixed installations differ greatly from those for portable applications. Connector offerings run the range from cheap throwaways to high-end boutique (hyped) designs providing obscure and inferred benefits. Make sure you consider the basics: how long is a cable assembly expected to last and whether it will be plugged in rarely or often. Note too that wires fished through raceways, chases and cavities require additional considerations with regard to safety and environmental tolerances. Most all brands and options can be sourced from Digikey, Newark and Mouser. Digikey has some of the fastest order processing available and their technical resources are stellar. Solder, flux and soldering tools are also offered by the vendors mentioned. In my experiences, only a half-dozen times was silver solder required, its necessity is rare.

For most uses a good quality pre-made cable is as good as anything else. The biggest problem is figuring out which ones are well made. It is very hard to make your own RCA cable with connectors that will survive the tugs that the molded plugs will take. Avoid pre-made connectors with big plugs and stiff wire. Most RCA jacks are not very strong! I only make my own RCA cables when I need something special or I do not have time to get a factory cable.

My favorite RCA connectors are the Switchcraft 350X series and the smaller Neutrick connectors. I prefer the Switchcraft ones because they are smaller than the Neutricks. Avoid large, long RCA connectors. The put more stress on the RCA jacks that they plug into. Most RCA jacks are not very strong. Most modern equipment uses custom, hard to replace RCA jacks. In most cases, these cables are not used in wet or corrosive enviorments or at high currents. Often gold plating only adds beauty. Don't pay a lot extra for gold! Switchcraft and Neutrik connectors are avaialble from Newark Electronic, DigiKey and many other vendors.

Since I rarely make RCA cables and avoid them for anything over six feet long, I do not stock wire for making this type of cable. Most modern audio gear has fairly low impedance outputs and bridging (high impedance) inputs. Almost any cable has low enough resistance and capacitance to work extremely well. The common exception is the cabling from a Moving Magnet cartridge to a phono preamp. I look for a good copper shield (it may be "tinned", a nice size (about 1/8 inch to 3/16 inch), and ease of stripping and soldering. Avoid CATV cables, they usually have aluminum shields which will not solder properly.

I still solder almost all the audio cables that I make. Soldering is a art (skill) as well as a science. It took me a few years to learn how to make all my solder joints good and reliable. You need the right iron and solder for the job.


CABLES BETWEEN A PHONO PICKUP AND A PHONO PREAMP ARE SPECIAL !

Moving magnet cartridges have very high inductances. Low cable capacitance is usually very important. If the total capacitance of the cable plus the input capacitance of the preamp is too high, They will form a circuit that is resonant in the audio region. I noticed this years ago as a large dip in the audio level at about 12 KHZ in some record playback systems. Use low capacitance cables and keep them short!

Phono cartridges have very low outputs. Use cable with excellent shielding. Hums and buzzes are often due to poorly shielded cables and poor grounding. This is an area where poor practices are occasionally OK but following good pratices will often avoid trouble.


BE VERY SLOW TO BUY EXOTIC CABLES AND CONNECTORS !
In some ways they may be better but spending hundreds on special cables is usually bad engineering. The money will usually buy much more elsewhere.
