My tubed 30 watt amp and preamp have no IEC connection. Can the existing cords (skinny ones) be shielded by wrapping foil or adding braid by cutting of the plug, slipping on the braid, connecting a new plug and connecting the braid to the ground pin? Is this worth doing,
or is it all or nothing? Also how can all those too long power cords be handled. I believe they're the source of the slight noise I'm getting with the volume at 2 o'clock and why I'm asking about shielding. Can individual cords be looped into a bow and be held by ties to seperate them? Can they be shortened and add new plugs? Or???
Follow Ups:
There are many things that can be done, and for all of them, you must be very careful when working with AC power situations. If you do not have any experience or hobbying chops, then seek out the help of someone who does, or get the local TV repairman or electrician to do this for you.Actually, the easiest thing to do would be to get one of the Volex cords that already has shielding, and use them, and you could always cut off the wall plug and substitute a better one later, or at the same time as changing out the cord. The Pass & Seymour 5266X is an excellent plug, and is quite reasonable in cost.
The Volex cord information can be found in this Asylum, just use the search engine. A pre-molded cord can have the ends cut off to use as raw wire, the cost of the pre-molded Volex cords is so cheap, that it is often a less costly option than trying to get just the raw cable by itself.
If you wanted to try just shielding your existing cords, you can do so with a copper braid, which canbe had from a suitabl diamter coaxial cable (which RS carries several different sizes by the foot). Just be sure to use copper braid, not aluminum. Then, it should be grounded at the wall outlet ONLY, and not allowed to touch the chassis of the component. I would also place Heat Shrink over the braid then, or at elast, wrap it in electrical tape. Just aboutthe only way you will be able to do this safely, would be to cut off the 2 prong plug, noting the polarity of the prongs, and what wire is connected to which prong, and using a three pin plug, so you can hook up the braid to the AC ground pin.
Like I said earlier, it would be alot easier and safer to just get a whole cord and start from there.

Twist them together, shorten them, loop them?
Spacing, right angle crossings, keeping power away from line level, digital (and or video) away from analog, phono away from everything.If you sit down and plan it out, or diagram it, then you can dress cables out to be as far away from each other per the above preferred priorities for as little coupling between them.
