Horizontal Output Transformer Tip

If so, probably not by much. The steel chassis has a lot of thermal mass, it's not just going to soak up heat from the small flyback frame like you would think. If it were made of aluminum, sure. For the most part, a correctly aligned horizontal oscillator and a small muffin fan will be more than enough to keep things happy. Plus it's easier than lifting the transformer off the chassis, and potentially damaging something in the process.
