So I bought a spider IV half stack from my buddy who blew one of the outputs on the head. According to him, you need both to use the speaker cab, one output goes to the left speakers, and one goes to the right speakers. He apparently didn't realize this until he blew one of them, the right speaker output. He removed the part and I can't seem to find the replacement part anywhere online, and I don't know how to solder. Can anyone help??
Heres some pictures of the part he removed from inside the head
