Use a shielded cable with an outside diameter
matching the bore of the RCA connector, typically
between 8 and 9mm.
The cable I used was sort of telephone- cable.
Between the wires and the shield a plastic foil was
wound which made it easier to remove the wires
because of the low friction!
Cut of the desired length and remove the inner
cable-parts.
Preparing the shielded jacket (2)
Have the shielding exposed over a length of 10mm.
Cut away a small flat section of the flange of the
ferrule (see picture in Ingredients).
At about 25mm from the edge, cut a small hole in
the sleeve.
With a tooth-pick, pinch a small hole through the
shield.
Insert a (ground) wire into to opening and strip
the cable over a length of 10mm.
Mount the ferrule and the stripped wire as shown
right.
Fold the exposed ground wire backwards over the
flatted section of the ferrule.
Push the ferrule further in and make sure that the
ground wire is between the ferrule and the shield.
Cut off 40mm shrink-sleeve and shrink it over the
prepared cable-end in such a way that the
shrink-sleeve covers the flange of the ferrule, but
leaves an opening for the signal-cables.
Prepare the other end the same way, except for the
ground wire.
Make the length such that the sleeve of the
conductor assembly will extend ~10mm at each end,
see picture at the right.
Final assembly
Twist both signal-cables and join them together with
small pieces of shrink-sleeve.
Insert into the jacket.
As described before, the sleeves of the
signal-cables should extend ~10mm.
Insert the assembled cable in the RCA connector.
The conductors should end up close to the solder
locations, see pictures right.
Cut the conductors to the proper length and solder
them with the silver-tin solder.
The solder must look shiny to indicate a good solder
joint.
