[Hallicrafters] Did Power Line Voltage Increase from 110 to 120V?

[Dean Chesterman]

The line Voltage has been bumped up over the years since the 1920s.

In Alberta, the Source Voltage at the Transmission substations has been 
125 Volts since the late 1970s and was 120 Volts since the late 1950s. 
When the farm was electrified in 1952 most people were concerned because 
they had 115 Volts on the line and the old AC/DC radio was only rated 
for 110 Volts.

Note that this is a limited sample of one, and voltage may vary.

(120 Volts for Control, 25 kilovolts for Station Service
and 144 kilovolts for doing something useful!)
