Since the two sections of each rectifier are paralleled, the min series impedance is 75 ohm, not the 150 from the chart. The stated sec resistance on the schematic is ~40 ohms so internal impedance is still less than spec. One detail often overlooked is that the primary resistance as reflected to secondary should also be added in to the meas secondary resistance. In this case it might add 10-20 ohms to to the 40 already present. One possible solution would be to add say 20-50 ohms resistor to each sec winding. Another would be to add an NTC IRL to primary for added reflected impedance.
