Note 1: All resistor values are ±1%.
Note 2: C1 = C2 = 0.1mF.
Note 3: S is a 6V transient suppressor.
Note 4: D1 to D8 are Schottky diodes.
Note 5: The fuses are optional to prevent AC power line crosses from compromising the transformers.
Note 6: The 68mF is used to keep the local power plane potential within tolerance during a surge.
