As the title says, I just got a Matts D200HC amplifier that somone attempted to repair, It is missing the Output mosfet's. Does anyone know what the original part number is for this amplifier! Thank you in advance!
If no one can tell you definitively, you may want to try the IRF3710Z. The D300HC used the IRF3710. I've had better luck with the IRF3710Z in the amps that use the 4080 driver IC.
