It is so simple to find out what the line voltage is.  Just stick the VOM leads into the outlet.  
You also should be sure what you are measuring - RMS voltage or peak voltage, or something in between, due to your particular situation.  Check with your electrician to be sure that your outlet is wired properly.

I have always gotten a straight 117 volts here in Baltimore.

Carl decades ago the line voltage was closer to 110-115 vac whereas now it is closer to 125 vac. A stock 20a plugged into todays AC mains will literally "cook" the tubes. Sure a variac is the right choice here, but the poor 6u8A is still the weak link. The 6MU8 is just a beefier alternative.
