I just picked up a blind NARC that has a K7000 (specifically a k7935) in it with some badly cracked and leaking caps (C56, C57, and C50 are all cracked and have oozed) and some serious blackening around the traces. On desoldering some are lifting away, but I can address that when I do the cap kit. I checked the HOT off the board and it's reading within range, and the flyback physically appears okay, though I'll be swapping those as well anyway. Before I go about this I'm trying to figure out what could cause those caps to fail so bad so I don't end up just frying everything again. All of the equipment appears original, though I can't seem to locate an isolation transformer, nor a place where one would've been mounted. I'm wondering if that's the issue. Anyone know where the iso would be in this cabinet? I'm assuming it's supposed to have one. I checked the schematic and don't see it. As an aside I found a property tag on this NARC from the arcade I worked at when I finished high school, it was one I worked on 22 years ago.
