Yep, looks smoked all right. Lol. Been there, that’s frustrating.
It would help to know more- photos of both sides, what the whole set-up looks like, etc. Did you use the edcor transformers? Did this happen the first time you plugged it in or what were you doing when this happened?
The 20uf and 33uf cap connections look a little charred too. The 150 ohm 5w resistor looks weird to me, but I’m no resistor expert. Double check the values on that. Check the values on all the components one more time for that matter. And double check your wiring from the power cable to the transformer to the board.
