Dear Quang,
I live in Scotland (240 volts AC supply, 50 cycles) and also bought US equipment ( 120 volts AC, 60 cycles) The solution is to buy a PS Audio power regenerator. There are 3 models that are suitable for this purpose, and all available on Audiogon for reasonable prices. P 300 is for front end equipment, CD player, pre amp etc, the P 600 is for power amps with a medium power out put and the P 1200 for big amps like the Krell. All of these models will take in the home country's voltage and cycle rate and turn out a variety of voltage and cycle rates to suit. The P 1200 I have is plugged into 240 volt mains and is tuned to step down to 120 volts and 60 cycles.( Other voltage and cycle rates can be applied ) It does a fantastic job of cleaning up the mains supply, your Krell will never have sounded better. I suggest you check out the PS Audio web site and some independent reviews. In my personal experience the customer service dept at PS Audio is terrific and helped me solve my problem despite the fact that the unit was second hand.
Jonathan Hart of PS Audio answered all of my nieve and sometimes stupid questions over a period of weeks with patience, humour and a genuine interest in finding me a solution to my power supply dilemma. He is extremely knowledgeable about his company's products, the current models and the units that are no longer in production, any questions he is definitely the main man. If I can be of any further assistance please don't hesitate to contact me .
