I had to send my little NAD amplifier in for a repair recently and I took out the little bridging plugs and put them in a safe place. I now can't remember what that safe place is and I can't find them.
NAD Australia want $9- for the pair of them plus $25- postage and I'm wondering if using a spare set of RCA connectors with a short fat wire will work better than the current 600mm length of spare cable I am using to do the bridging between the Pre and Power sections of the 325BEE.
Naturally I could simply pay for postage but I'm a tight-**** and also cash strapped at the moment.
If I solder some up does the conductor wire size make any real difference over 50/100mm?
Also is shielding needed?

My original shorting plugs were just solid metal without any shielding or insulation.
I made a pair in the way you mentioned for a second amp that was without the plugs and they work just fine. I think I made them around 100mm long.

Sound like something I do.
Just use any insulated wire as short as possible I reckon - too short to have resistance or radiated pickup. Just long enough to provide finger grip.
However, have you checked for the originals at the back of your sock drawer?

My sock drawer is a wire basket and I just checked the floor. I know as soon as I make a set up the originals will turn up. I have checked all my pockets.
You can use 1/8" Aluminium solid bar, then bend it around a terminal screw driver handle.
Then then cut it to the correct length and file the ends round.

There’s a long list of items that are historically located in that “safe space” in my household.
I too made a short set of jumpers using rca plugs for my NAD.

The current of signal inter-connections is generally only fractions of a mA and any practical wire gauge will be fine for the signal but there is a possibility of heavy earth currents between separately powered units in your system during fault conditions, so you still could need a comparable amount of copper for the ground or shield connections between separately powered units in your system, anyway.
Whether you use shielded or a twisted pair of wires over a short distance like 100mm would make little difference. Leaving any external signal connections without an earth screen of some kind though, is asking for trouble with RF and environmental noise ingress. Simply twist the insulated wires together closely, for best performance over short distances. If you find that difficult, a vise or even a pair of vise-grips can help keep the pair-twisting even, straight and tidy.

If I leave the house for an extended time, I hide stuff like checkbooks & documents in case of a break-in while I'm gone. I make a note of the hiding place(s) and carry it in my wallet.
