Folks:
I am building a small power supply for an ACP+ and wondered whether it was worthwhile including a couple of these ferrite cores in the mix. My thought was a single loop of the hot and neutral 18 gauge wires through their own ferrite core before the transformer.
Happy to just test them out, but not if I'll be running afoul of smart design theory.
Regards,
Scott

Those look like the type of core intended to be used with single wire passthrough... they might make good candidates for your V+ and V- rails.
The more common arrangement at the AC line input is to use a toroid form with 2 or 3 turns of the hot and neutral wrapped around it.
Don't worry about audio effects. Ferrite, depending on it's formulation, particle size and a bunch of other really annoying math, seldom has any effect below several megahertz.

Ferrite clamps for power cords (AC mains) are supposed to work with one wire, no loop. More important is the material. It seems that "material 75" clamp is at least as effective as a second order filter with common mode choke and capacitors.
yes mix 75 & 77 are good choices.
while some ferrites are only large enough for one cord loop, in general the more loops the better.
