Rockford Fosgate Prime R500-1D

[S Merlington]

The power supply fets are defective in this amp.

Does anyone know what fets i can use in this amp??

The orginals are marked BN0X3F

 

[Perry Babin]

That doesn't look like an FET part number. Are there any other numbers on the face of the transistors?

 

[S Merlington]

All the markings on the fet are

T460
BN0X3F

Thanks Perry,

Would 3205's or z44's work or should I try to order the originals

3205

See if Rockford has released it. If not, they should be able to give you the values.
