Default Cathode follower anode resistor.

Just been doing some work on an old scope. In the vertical amp they use cathode followers to drive the Y plates but instead of taking the anode straight to HT, they have a 100R resistor from HT to anode.

Apart from said resistor dropping the voltage a tad, what would be the advantage if any here?
