Hi folks, thank you all, I'll try this chip quik tool. I wrote wrong, it's not smd board but it has vias both sides. I repaired some amps before but most of them were single layer pcb. Founded another little problem, it's the green/red LED that doesn't light for green. Maybe there is the circuit protection that melted first than anything else I hope. I'll research this tool but now I'm sure that I need to invest in some better tools. I pulled the caps out, there wre broken vias. I will take some pics later! Thank u!
