Good afternoon friends of Yoreparo.com, I am repairing a guitar amplifier brand Line 6 model Spider III 75W and in the output card of the amplifier I see that it is missing the poweramp IC. I have not been able to find the diagram so I don't know what the IC that this built-in amplifier carries since its manufacture. The only thing I can see is that it is 15 pins. Has anyone repaired this amplifier model and knows what component is missing?

Can someone provide me with a copy of the diagram or service manual of Line 6 SPIDER III 75W? ?
Can anyone share any picture of this spider powder board or power board of Spider III Line 6?
Thank you very much and greetings from CDMX
