Ok, so I got my parts in, found a big stash of 2N5320 and 2N5322 transistors, and messed around with this again.
I'm using the CineFAQ troubleshooting steps because I'm popping a breaker with the monitor hooked up. I am testing with the ribbon cable connected.
Right now, I've stopped it from burning up parts, but I keep shorting the 2N3792 in the vertical amplification circuit between the emitter and the collector. The monitor will typically go for about 30 seconds before popping the breaker, and then I find the transistor shorted. Right now, that's the only part going bad.
Now, here's where I might have my problem.
At one point, I replaced the two .18-ohm 3W choke resistors because I had one that had some burn on it. Got the flame-proof kind. Well, while reading the CineFAQ, it mentions that they should be NON-INDUCTIVE and not wire-wound. So, I'm guessing I need to order the proper kind now.
But I'd like to know if this is enough to cause the problem with the shorted 2N3792 or not. If I need to order more parts, I'd like to do so while I'm ordering the right resistors....
