I can't see if any cracks by trace. Too small. I replaced the Transistor 2n2907a, it plays longer, cuts out a few seconds then comes back on for a while, the twisting of Transistor isn't cutting in and out like previous video. So I'd say it's a little better, but not fixed. I can't get it to cut out manually. I moved every wire and can't replicate it. It will cut out by its self, when I touch certain metal parts, with a metallic probe,like the Transistor I can hear static clicking in speakers like some sort of discharge. I go to sleep thinking what it could be. When it cuts out the d2 led on the b side remains lit.
