replacement mosfet BR80N08 amplifier class A / B

[Albis2985]

I need a replacement for this mosfet that is used in an amplifier source, since I replaced the 4 80n08 with the 80n06 but they get quite hot.
Then I put two of the 80n08 that survived and do not heat up at all connected one by bank since they are in parallel

Are these output transistors?

 

[Albis2985]

No Perry are from the power source

 

[Perry Babin]

You likely have an open driver transistor or more likely an open trace.

What make/model amp?

Perry one of the 80n06 mosfet was defective since the amplifier is working fine, I checked what you told me about the conductive transistors I changed them but the problems continued in the end I went back and took out all the mosfet and one presented leak
