I'm 99% sure the SCR is installed properly. I do have a picture, altho i don't seem to find the way to include it into my post other than hosting it myself somewhere on the web and <.img> it in my post. I am not very familiar with forums.
However, I highly suspect the output transistors I sourced locally to be the culprit. They just look 100% like the one I received from china, but they are both a little different from the one I pulled from the unit. I wasn't that suspicious first cause I thought, well they were most likely manifactured many years appart so they might have changed the silkscreen a little bit. But why would the same channel blow again if there was a short caused by the SCR and not the older set of transistor, which i would assume is somehow weaker since it has much more hours of work on it.. Anyway, now i am left with only chinese transistors, and I guess I don't reallly want to put them in. I'll try to find newer generation (not discontinued) to replace them so I can rule out the bad Transistors hypothesis.
