Hi!
Having weird issues with this subwoofer amp. Once upon a time it buzzed when in standby and no signal coming in, I changed few little caps and this fixed the problem for many years to come. Now this thing started to take huge load of the wall, tripping the breaker and making varying scratchy sounds with no input. I've measured main caps with Peak Atlas ESR70 and they seem to be fine. There is one tiny Nover cap 10uF 50V, it has ESR of 2ohms. Is this normal or should it be lower? Manual of the meter says that 63v 10uf could be as high as 9ohms and still be good but I can't be sure about this because it's in German.
I'll check connections closer and resolder ones that look bad but other than that, I'm pretty lost with this.
