Ground zero gzpa 1.4k hcx question for output fets

Hello, I have this amp for repair, but iam not sure if the technician before put the wrong output mosfets. Maybe someone can check which one are installed. It's the amp with the buffer stage between audio drive board and output filter.

I asked the manufacturer, but they didn't answer.
 
Hi,


I owned 3 of those amps myself.
Unfotunately I did not check those amps without the heatsink clamps.


If you ask Ground Zero for the service manual of the 1.4K-HCX they will probably give you the internal diagrams for this amplifier.

You can read the exact part number out of the diagram.


They always provided me if I asked for information.
