Broken mosfet after changing rectifier capacitor ( Class AB amplifier)

Hello, I have a old Cerwin-Vega active subwoofer subwoofer ( 2009). I changed the big capacitors and some other small ones. I tried to power on the amplifier and a MOSFET near the big capacitors started to smoke ( IRFP150NPBF). The is another IRFP150NPBF mosfet and two IRFP140NPBF on the other side of the board. What can I do now? Nothing on the board seams to be burned or damaged. I tried to check the new capacitors and they seams to be ok. I'm concerned about the power amps and the circuit that controls the mosfet on the power supply part. Before ordering some new parts I want to be sure of what is OK and what is broken. Any help is welcome :) I'm not a technician, I'm very good at DIY projects and I know the basis of electronic.
