For some strange reason my voltage has been holding steady at 118-120 for
almost 2 years now. Before that it was 124-128. Even so I still use bucking
transformers on vintage gear and run at around 110-113V where everything
runs nice and cool.
The utility company has been doing a lot of "forced work" in town since the
Selectman read them the riot act about losing power every time a crow
farted. The Dec 2008 ice storm was the final straw when power was out for up
to 8 days.
