Help

i am changing a Heathkit SB-200 form 220 volts to 110 volts. (no choice)
on the 4 wire grid on the underside of the amp,     which is HOT and which is NEULTRAL    NO' Screws 1,2,3, or 4.  I know green is Ground
i am not sure how to tell which would be the hot screw on the 6 screw wire terminal, i know the 2 outer are ground.

thanks very much
