The power supply fets are shorted in this amp ..
They are maked PFB6000 .. Anyone know what i can replace them with ??
The amp uses 100 ohm gate resistor for the power supply fets and A1266 and C3198 as drivers

Most of the amps in this series used IRFZ44s. With 100 ohm gate resistors, you don't have many choices. The IRFZ46 and IRFZ48 will work in many of the amps using 100 ohm gate resistors but you must test to confirm that there isn't a problem. With the Z48s, I'd suggest replacing the gate resistors with something between 47 and 75 ohms.
