    Can't find VR301 on the board diagram. Should be on the driver board. Found an interesting arrow down towards the left-hand bottom between C303 and C304 and right above R317. Think that is it?

    Got a better service manual with a complete schematic. Found it, between R399 and R400. On the schematic, it's labeled as VR301. On the board layout it's mislabeled as VR401. Mystery solved.
