Hi I have RP8 model also with that black gunk stuff and rust problem. But I am also replacing all that Yiiiiiichon caps. I will tell me friend to replace all of them small ones and big ones with same V and uF. I will order from different sellers, what can I do. Here in my country they don't have Nichicon or Rubycon, only Samwha and some low quality caps like that

But I am strugling to see because of that black gunk and position what values are those capacitors on the picture that I circled if someone can help me so I can order them too, and to tell me if they are normal caps or low esr. Picture in attachment.
I mean when you do some maintenance it needs to be done properly by replacing all of them

right ? what do you think ?
