It can give an OUTPUT 1,875Watt @4Ohm Load (3xIRFP250)
The L3 coil\inductor will simply melt based on that core

No..blue and yelow are lower..look here:
Toroids - Micro Metals / Iron Powder

Red is just more famous..i also used red because i had no space for others since more turns were needed for the same inductance.
