This cable recipe is one of a series of designs I've built and offer to this forum as a thanks for being there sort of thing...
performance is rather good [but not the best in the world]
Cannard Digi cable
Recipe for Duck
Take one duck .......?
This came about one day when I'd mislaided my dedicated 75ohm digital cable, the nearest to hand was a silver twisted pair with cheap RCA's [25p each]. Well surprised at the improved performance I checked all the usual suspect and finally came to the conclusion it was the cable. This by the simple expedient of replacing it with the Digital cable I had now found.
Ingredients
1 x pair of resistors that form 75ohm [in t pad form]
1 x 0.8m blue vibration damper
2 x 0.9mm PTFE sleeving 0.7mm dia[internal]
2 X 0.95mm [4n/99.99% purity] dia Fine silver wire
2 x RCA plugs
heat shrink
silver loaded solder
insulation tape*
2 x clamps or a vice*
soldering iron*
silver loaded epoxy [optional]*
Expandable Woven braid [optional]*
Multimeter*
Sharp knife
First sleeve the silver wire in the PTFE.
Clamp sleeve and wire to table or bench and clamp the free end [to make a handle].
Using the handle twist the wire to get about 6 - 8 twists per inch.
As you release the pressure the number of twists unwind to about 5 per inch.
When settled down thread through blue tube. Slide blue tube through nylon mesh and secure with 70mm heatshrink at both ends….be careful not to melt the nylon, been there !!
Tape one wire and use the multimeter to locate its other end, tape again.
Solder or epoxy RCA plugs in place, at one end add the resistors across signal and earth. This is no mean feet, and I try to loose the res pair in the body of the RCA plug.
Place on a cable cooker* for 2-3 hours till tender.
You don't have to use silver ..copper will work though I'd suggest silver plated coper be avoided [I hate the sound of it !]
you can leave out the vibration damping tube plus the mesh braid if you want ...infact you can customize how ever you wish!
