Is there a wattage / amperage rating on this?

The main purpose of The Cleaner, is to strip RF from the mains cable, each
lead separately, so as to vastly reduce the "white noise" that then pervades
your system. This more effective on all solid state gear, as the multiple
diode junctions detect the noise (actually noise modulation of the RF) and
reproduce it, about equally in both channels. So The Cleaner instantly
improves width and depth of the image. On some equipment, it's quite
dramatic. It will work with any wattage and amperage.It will work in all situations where you have an AC supply.
It works best on pre-amps and source components (i.e. where there is voltage gain involved) and of course integrated amps.
It is not current limiting in any way, so it also works very well for power amps.

Where are you shipping from?

Is it still available?
