Thats to adjust the bias. You'll have to check the emitter's voltage and adjust it according to spec.

It looks like you have two bad caps (C213 & C119) according to the pics. Or their just "sun burned" and might be perfectly fine.

I think their "sun burned", the amplifier works good

Not a good idea to touch those. If you can put it back where it was before, you should be alright, but I wouldn't risk running the amp otherwise.

A little recommendation from someone that recapped and cleaned one or two of those: "Always mark those with nail colour or tippex before u start cleaning the amp"
