Ive got a k7000 in vertical collapse.I found that IC3 was burned up. I replaced it and its getting way too hot. If I leave the monitor powered on longer than a minute or so, it will fry IC3 again. Ive swapped out tubes, the neck board and the remote adjustment broad and there was no change so I'm sure the issue is in the chassis itself. Here is what the first burned up IC3 looks like. What could be causing this issue?
