Moving to England and Kurzweil Technicians say that all Kurzweil instruments have adjustable power supplies to handle the 220 volts there. Does anyone know... is it easy to adjust at home, or does it need to go into the service shop? Thanks. Babbs

It is easy to adjust at home, however
I would personally bring it in to a service center. Kurzweils warranty regulations
are on the strict side. If you to need repair
at a future time they might try to use that as
an excuse to void a warranty.
Better safe (and slightly paranoid) than sorry.

Interesting question. I just looked at the back of my k25xs and found a small pannel located just to the right of the power switch. This pannel consists of, what appears to be, 4 micro buttons which are labeled: 100, 120, 230 and 240.
