Hello there...
First, I don't know if this is the right category for my post. If it isn't, someone please move it where it belongs.
I would like to tune a bit my preamp in my receiver(Denon AVR-1802), but I don't know exactly what I should be changing over there. I think the caps are very important, and maybe that should be a first target.
I attach a picture with the preamp pcb, and I hope someone gives me some tips where I should be looking first.
Thank you so much...

Come on guys, no idea what is over there?
I am not looking for precise indications on what to do, general observations would help as well...
Unfortunately I don't have the schematic and Denon won't provide me with one(I sent them another email today, maybe it works this time)
And one concrete question, any idea about the values of the caps that have (???) next to their description? Is that nF? The B for the caps 333 is the indicator for the temperature I guess... Am I right?
What about the red ones? Unfortunately I don't understand much from what is written...
Thanks 🙂
