[Hallicrafters] Lets hash it over one more time.

The voltage span of 105 to 125 VAC is the range over which it will
perform, not the voltage that is best for it. Since engineers usually
specify an operating voltage +/- some percent. The design voltage is the
median voltage or 115 VAC. You can run your equipment at 125 to 127 VAC,
but I sure wont. The higher the voltage, the more heating occurs. The
proof of the pudding is to measure the filament and B+ voltages. If they
are higher than the manual voltages you are overloading the power
transformer and other components.
