I'm with the other guys. There may be nothing wrong with the unit, and its operating normally. Saying warm or hot, with no real numbers really doesn't mean anything. If you have access to a thermometer with a small "pointy" probe, then get us some numbers. F or C, doesn't matter, just as long as you relay the info correctly, and don't get them mixed up.
Just because a TO-220 package can be, and is, commonly mounted on a heatsink, doesn't mean it needs one. Its particular use, and how much power its really using, will determine that. Also, how big of a heatsink, if one is needed. That's something the designer has to figure out. I can go on a big rant about numbers, and quantifying data. That's something that seems not to be emphasized today. Numbers count ! I have a little money, and Bill Gates has money. You think numbers matter, in that example !? I don't know squat about electromigration, other than it doesn't happen at the PCB scale (remember numbers). However, a PCB trace can carry only so much current. Too much, and it will simply act as a fuse. Don't think that's an issue on a nixie clock. Can't say, either way, on an X-Box. Maybe there was an excess current issue on one of the X-Box traces, and some fool heard a new big word ? I spoke the word "euphoria", here at the office, and one idiot overheard it, and misused it for months.
