Bedini Amplifiers - two different builds/layouts of the same model amp?

I've got two Bedini 100/100 amplifiers here and I opened them up and they both have two completely different builds to them. The labeling, chassis, model numbers, etc are all identical between the two. It seems to be the power supply that is the main difference.

One has one transformer with 8 capacitors. The capacitors are about the width of a soda can and 1.5x the height. They're almost touching the amplifier boards above them. This one also has all the fuses located on the back panel, whereas the other has them internal.
The other has 4 times the transformers but half the capacitors, and the capacitors are also smaller.

Does anyone have any info on why there might be a discrepancy between the two? A mid-production design change or is one of them a one-off/custom job? They've both got John Bedini's initials on them on both the power supply and amp boards so I would think they came from the factory this way.

In most magazines I've seen I would think the 4 transformer variant is the more popular one, because it is heavier and matches the advertised weight. The one with the larger capacitor bank is noticeably lighter.
