Can anyone help me save my Kora Explorer 90Si

I had a problem with my:
Kora Explorer 90Si
I friend told me that I have to change one of the elements - the most bottom-right one

But I dont have its parameters- can anyone shoot one picture of his own, please?
I found a person who can rebuild it but he needs the exact info about this part and mine has no text on it - someone has removed it.

Any help will be highly appriciated.
Aball repaired my Kora amp, but through a few phone calls, I found him to be pretty rude and arrogant. I guess if you need it fixed you will do what you have to do...
