46-1213 Schematic Question
#3

Hi Larry,

Usually you'll want to attach the hot side of the power line cord to the power switch. That way when the switch is off there is no source of voltage other than the power switch. Looking at your schematic you have a situation where the line filter caps (75A and 75B) always have power on them when the power cord is plugged in. I always rewire them to the other side of the power switch so they only have power when the switch is on. BTW these caps should be replaced with Y2 safety caps.
