Default TDA2009 PCB design check

Hey all,

I'm trying to build an amp based on ST's TDA2009 chip in bridge mode. I've used the bridge circuit from the datasheet.

I've previously built the circuit on a pcb but the chip went hot fast. I checked the connections and there were no short circuits. I'm not sure what went wrong.

I've redesigned the the pcb and I'd like to get some help if I did it right this time. All ground points are connected to a ground pour. Images are in the attachments
