The amp has been designed to be an ideal upgrade for builders wishing to step up from Gainclones. This amp will kick out the power where Gainclones fall over, yet still maintain a sweet sound. The use of n-channel MOSFETs in the output makes the amp easy to source parts for as well as being very rugged. Provided that high power MOSFETs such as the specified IRFP250 are used and the appropriate fuses are used on the board, the amp should shrug off short circuits at the output.
With the recommended supply voltage of 41 V per rail, 160 W RMS into 4 ohms is achievable, again if the recommended IRFP250 devices are used. The use of less powerful MOSFETs will mean you need to use higher load impedances and/or reduce the rail voltage.
