Rectifiers?

According to Marshall amps the first Plexis had full wave bridges. 6 diodes for the 100 watt and 2 for the 50 watt. Then in 1968 the 100 watt was changed to a bridge rectifire while the 50 watt kept the full wave 2 diodes. Has anyone seen a schematic with this early 6 diode rectifire? And why is it that later 50 watters had 4 diodes 2 in series on each side I think. I´ve also read that there is more sag in a 50 watter. Does this means that the 50 is not as good amp as a 100 watt?
