I can’t damage the amp or the speakers by running the 4ohm taps? It appears McIntosh engineered the amp to run the same wattage at 8, 4, and 2 ohms.
No you will not. The autoformer in the MC402 maximizes power transfer between the amplification output stages and your speaker as the typical solid state amplifier will typically be half as powerful going into 8 ohms as it is into 4 but not with the McIntosh autoformer. So the McIntosh is comfortable driving a 2 ohm load as it is an 8 ohm.
