From the MC8207 owner manual
Power Supply CircuitsSee page 15
To compliment the design of the MC8207, there is a high current power supply for the five power amplifier channels. Refer to figure 21. The very large Power Transfomer, has toroidal windings on a toroidal core and can supply over 35 amps of continuous current. Refer to figure 22 (golf ball is for size comparsion). It is enclosed in the legendary McIntosh Potted Enclosures and weighs over 12kg. The super size main filter capacitors can store over 340 Joules of energy for the seven amplifier channels, necessary for the wide dynamic range that “Digital Audio” demands. The power amplifier draws high current from the AC power line. Therefore, it is important that they plug directly into the wall outlet.

Where’s the second transformer? Am I missing something?
The very large Power Transfomer, has toroidal windings on a toroidal core and can supply over 35 amps of continuous current.120V X 35 amps = 4200VA. Just a guess the transformer is rated at 5Kva.
In the manual it says "To compliment the design of the MC8207, there is a high current power supply for the five power amplifier channels". And this is a 7 channel amp so what about the other 2 channels. And why is there two boxes, what's in them if there is only one transformer. I am trying to understand what is what.
