DANGER - High Voltage Present! Follow along at your own risk.
This video demonstrates how to measure the rated output power on the McIntosh MC2505 and how to use that measurement to calibrate the front panel meters.
NOTE: I shot this video with the unit on its side as I had just finished the amplifier DC Balance and Bias adjustments. For best results, make the meter adjustment while the amp is sitting in the normal position.
