B+ voltage on zenith k731

Appreciate your thoughts Chad, so i went and look at the back of my k731 which stated 117v -ac/dc, then measured my line V which came out 118.1v and said wow, that close.
But after thinking for awhile, this line variation wont even matter (except for filaments) if we can adjust the voltages going out to the circuits by using the optimum resistance, paricularly the Resistor thats in series with the selicon diode... My next chore would be to monitor the average of my line voltage and calibrate my B+ from that average so more or less i'll be on target. If there is a better way please let me know?.
Am like blindfolded right now as i cant do anything if i dont get that B+ specs. I'll probably wait for that website to get fixed. Meanwhile, somebody wants to HELP???.....my anticipated thanks.
