Ah, just as I suspected. But I’m a little confused. Why are you concerned about the PCB when you have identified the transformer as dead. How do you know there’s anything wrong besides the transformer?I metered at the transformer's output direct and it' now clear that it crapped out. I get 0.5 - 0.4V AC. No damage or dark spots are visible anywhere.
At this point, since this is a simple circuit board, I'm wondering if I could just replace everything except the coils...and start almost from scratch? I sincerely don't know what crapped out and maybe I could source better components than those that are on that PCB...? Could that be a viable option?
I'm including a pic of the board, again.
