Help Helix A2 Competition amplifier component

Could someone please help me? I'm repairing this Helix A2.

It came with several problems at the source.
Firstly, I would like to know which component is missing and the correct value of the capacitor that was replaced.
Both components are circled in yellow.

Thank you in advance to everyone who can help.

I also didn't find anything, the only solution is to wait for someone who has the same amplifier and can take a photo of the place.
I didn't get around to connecting it because I haven't yet bought the other components that are damaged, but I think I'll have them assembled and risk calling to see what happens, but looking closely at the solder mark and the distance, it gives the impression that there's a zener diode there.
