I've got 2 active amps with damper voltage doublers. A hi-fi amp (1 x 6BY5) and a guitar amp (2 x 6W4). Thousands of hours on the hi-fi, hundreds on the guitar amp. Had another hi-fi, now retired, with 2 x 6AX4 doubler. Thousands of hours. Never had any issues, never replaced a damper.
Recommend a relatively small (40 uf or less) pair of inital caps with a great big one after the L or R. That will keep the dampers happy and your ears happy, too.
