Seems as if my BC337s aren’t holding up. I re-soldered new ones into some dead modules I had and they came back to life so the 2SD1041s and tip102s were still good. The BC337s I had on the BD649s didn’t burn up and those are the modules I have had the most run times with not sure what to make out of it. I must be using the wrong BC337s or need something stronger.
