This may sound like a tough question, but it probably isn't. The unit in question is an Infiniti SM785 monitor (17", 1996). I acquired this years ago and obviously attempted a repair, because I left a large TO-3P transistor (Q604) removed from the circuit, and of course it is long-since lost. Funny thing is, it's not the horizontal output. Doesn't seem to be a pincushion amp either, because the monitor will not start without it - a regulator of some sort maybe?. Anyway, there were several smaller blown transistors nearby, so I replaced them and then attempted to take a guess on the missing TO-3P. The only one that allowed the monitor to power and work normally was an NTE2324, however I only left it on for a few seconds because I didn't want to risk damaging anything. Does anyone know what the function of that transistor is, and what would probably make a good sub?
