A few of us remember when the line voltage was 110 (+/_) (Back when?? )Then the utilities upped it to 115v....then 120v...Now I have 125v. It's been a gradual increase over several generations. Old gear is most happy with their specified primary power source of 110 or 115v. It might tolerate +10% but not at 120v+ line voltage. Years ago I changed over to 130V incandescent bulbs because the 125 line was taking out the common 120v variety after a week or so. By all means do what is necessary to adjust the primary input voltage back down to what ever the manufacture specified at the time. Then fine tune it for proper filament voltage. Look for a good ole RMS Line Meter* and a Variac from your favorite ham Swapmeet. Or check on line for Expanded Scale Scale (100-140VAC) Voltmeter Kit.
