Unless otherwise noted, you should take all voltage readings with your meter black probe connected to the chassis. There are four power transistors on the heat sink. Two of them should have about +50VDC on their casing. the other two should have about zero VDC on theirs. Those two should have about -50vDC on their emitter legs, which connect to the 0.22 ohm 5 watt resistors nearby.
Please refrain from saying things like "No reading" or "nothing" on the meter. Zero volts is still a reading. Nothing or no reading to me means the same thing as not connecting your probes.
