Hi, I am trying to repair this beautiful amplifier from Denon, a poa 1003 from 1978.
The right channel goes into protection and also produces a distorted sound.
unfortunately there are no wiring diagrams so I am checking every single component and trying to replace them with those of the working channel.
So far I have only found this component not working, but it is not the cause of the defect.
Some of you could explain to me what it is, it's the first time I've seen it and I can't find anything on the net.

I would say it's an input filter. Note the IN terminal near. Check if it goes to this terminal. Could also be a muting relay.
Do You have DC on the output ? Measure before the protection relay if there is one.

Yes, the center foot (on the side where there are three) goes to terminal IN.
on the channel that distorts and goes into protection this component was defective, then I put the channel one working, but the problem remains.

Looks like a nice amp.
This might make it easier to make sense of some of the parts and schematics:
