You are out of luck, I had exactly the same problem when I moved from the US to France. All newer Krell equipment (including the Showcase processor) has a voltage/frequency chip on the power supply. If you try to use a step down transformed to go from 230V to 110V the chip will see a frequency error (50Hz instead of 60Hz) and not allow the processor to switch on. Two options; simply have the Krell agent in the country you are in convert the processor from 110V/60Hz to 230V/50Hz (this is what I did, not cheap though). Or alternatively, buy a power regenerator (PS Audio and others make them) that converts AC to DC and back to AC at whatever frequency you want.
Krell Showcase Processor Voltage conversion
Just bought an US 110V unit but to be used in my home country where the voltage is 230V. I have tried with a step-down transformer and it works fine. Since other Krell products like the KAV 300i voltage can be switched by changing jumpers, just wonder if anyone has experience on the showcase.
I do see jumpers for the both the primary and secondary cables of the transformers and two jumper slots unused.
Please advise. Thanks.
