On the heels of the thread about the Polyscience/Breville ControlFreak, it appears all-metal induction hobs have now arrived in USA.
The Panasonic KY-MK3500 is a 208/220v single phase hotplate that should operate on any home circuit that is wired for coil or radiant ranges. It is rated to 3500 Watts at the "old" 24kHz frequency (ferromagnetic pans), and 2500 Watts at the 90kHz frequency chosen for aluminum and copper, and switches automatically between the two. Panasonic claims its temperature settings and IR sensors operate through the solid glass rather than by a button probe or thermistor mounted on the underside of the glass. There is also a lighted ring around the hob to indicate operation and high temperature.
The unit retails for an average of $2,400, but one retailer was offering it for only $611, so I ordered one. https://www.ckitchen.com/p/panasonic-ky-mk3500-met-all-induction-range.html
Edit: I now see it is listed at $1,700! Amazon has it at $2,250.
