Have any of you ever measured voltages at UB10 or UB11 (Sony chips) on an SE/30 motherboard? I don't have a long enough cable to safely pull out the motherboard to test that. I am specifically curious if capacitors C3, C4 & C5 see a maximum of 5V or 12V. I suspect one or more of those 3 capacitors do see 12V since the SE/30 schematic shows 12V going into those SONY chips at more than one location. A datasheet on those SONY chips would be wonderful, but I can't find anything like that. The reason I ask about the voltages across C3, C4 & C5 is because I've be
