To start with some hard experimental facts, I took a power amplifier – similar to Figure 9.7 – powered by an unregulated supply on the same PCB (the significance of this proximity will become clear in ...

That’s Vc which is the collector voltage with respect to ground. By design, Ve was 1.5V, so Vce with no signal present is 6V and the power dissipation at that point is 6 times 0.75 or 450 mW.
