@jea48 From the MC8207 owner manual Power Supply CircuitsSee page 15 http://stereobarn.com/wp-content/uploads/mcintosh-mc8207-amplifier-owners-manual.pdf 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. |

Link to the video I uploaded on youtube where you can clearly hear the MC8207 buzzing loud. Also I have measured for DC offset in my AC line the the result was 0.9mV, which is not enough to cause the transformer to buzz https://www.youtube.com/watch?v=ucbBaD2eIgg |
