Yup, heard that one before about the filament voltage. Good old Loctals should fare well with increased line voltage we see today, and other than corrosion and improper removal from sockets may outlast many of us. So a Loctal should be good up to 122 volts supply if fed from a supply that was designed to run on 110 volts. Been a while since I had to toss one, other than glass types dropped on the cement floor.
