T2 is designed for 50Hz, 100Vrms.   60Hz, 120Vrms will work just as 
well, but then so would 25Hz, 50Vrms -  with 2.5v filament tubes, of 
course.  Similarly, American 120V, 60Hz refrigerators are commonly used 
in Asia on 100Vrms, 50Hz.  The only difference is that the motor runs 
slower on 50Hz, so it takes a bit longer to cool down the contents.
