704k isn't that far out. Basically your measured 166v is roughly half of 293v.
Better back up and measure AC volts on pins 4,6 of the 5Y3 - should be 240vac each pin to ground. Then 240vdc on pins 2,8. What's your AC line voltage?
Pins 4 and 6 are at 280 VAC, and 2 and 8 are at 310 VDC. Line current is 118 VAC.
