In Reply to: Plasma AC Noise posted by unclestu52 on December 24, 2005 at 11:58:49:
First of all, what 1-KHz tone? I hear no 1-KHz tone from my plasma set itself or in any of my gear as a result of the plasma set being turned ON in my system.Perhaps poorly shielded or marginally designed gear is more susceptible??
Follow Ups:
Apparently the 1kHz tone is imposed on the AC, which is why you can't hear it. It does contaminate the AC line, however. If you try to use a AC regenerator like the PS Audio's on a plasma set, there is an extremely high probability that the set will cause the regenerator to oscillate and blow fuses, if you are lucky.

If the 1 kHz tone is "imposed on the AC" by the plasma display, then how can the bybee filter enhance the performance of the display? I could understand how _other_ components might benefit from this filtering, but not the plasma display itself.
Has someone actually measured and "seen" this 1-KHz tone riding on the 60Hz AC mains on the outlet that a plasma set is plugged into? Which brand plasma set or do all of them induce the nasty 1-KHz tone?Where did you read about such a thing.... a reputable electronics journal or is this just more voodoo audiophile marketing to help sell expensive tweaks?
