[Boatanchors] More question on US AC voltage

[W4AWM at aol.com]

Hi,

US voltage now runs as high as 125 volts in some residential and business 
locations.  I monitor the voltage here at home and it swings between 121 and 125 
volts depending on the time of day.  I have seen it get as high as 127 volts 
for short periods.

Some of the older tube gear is rated as high as 125 volts, but that puts a 
strain on everything in my humble opinion. I normally use a variac with my 
vintage gear and keep it around 117 volts.

If it is necessary to have a transformer rewound, you can specify the input 
winding ratio and in that situation, I usually will have it set up fo 125V on 
the primary. I doubt US voltages will go any higher than that, but you never 
know.
