A European model will NOT work in America (or vice versa for that matter)
unless connected to the mains via a transformer. Additionally the mains frequencies vary which is another trap for the unwary. Unless the mains frequency input can be altered, the item would be useless in the USA. -- choro-nik ******* "WindsorFox[SS]" wrote in message news:U%%Qa.610$MK4.541@lakeread07...

There is absolutely nothing different in the power supply other than T901 itself, the power transformer. The impression that some devices are sensitive to line frequency comes from AC induction motors. It is indeed true that 50 and 60 Hz induction motor units are not interchangeable. However, a transformer is not a tuned device. The frequency over which I will work is broadly a function of the amount of iron in the core and the thickness of the laminations. However, this is not a sharp effect. In my laboratory I am developing a linear induction motor. This motor is impedance matched by an ordinary toroidal power transformer -- even though the driving frequency varies between 175 Hz and 400 Hz. It works fine. The problem with a European tuner in the U.S. relates to the deemphasis. In Europe, it is 50 microseconds. In the U.S., it is 75 microseconds. I do not know what it is in Hong Kong, because the manual doesn't state it. However, a U.S. buyer should be cautious. In view of the fact that the seller states the line voltage, I do not think that his intentions are dishonorable. |

In Europe the stepping is 25KHz. and 12,5KHz.. Therefore the tuner cannot be tuned to ex. 96.6Mhz. / Hans |

This means it can tune all U.S. frequencies. However, your mention of 12,5 kHz puzzles me. Perhaps you mean 125 kHz ? In the U.S., local stations are spaced 400 kHz apart, while stations in different locals may be spaced 200 kHz apart. |
