Ok so i went to a christmas dinner at my aunties. My cousin who is moving out had a amp that he never used (He has a better one). So i asked him for it and he gave it to me. Its a Ibanez IBZ528 MINI HAlf stack ( like the marshall mg mini halfstack). He told me that he got it repaired 2 or so because it blew out.

So i go home to find out its not working (no suprise there). So i take a look inside and find out the fuse is blown. I replace it and once i hook everything up i smell smoking ( OOOOO SHIITT) I turn it off and find out a piece is starting the smoking. It looks broken while the second one looks fine.

It looks like this.






The black and white thing is causing the smoke and what is it called?
