Your video link is asking me to sign in. I am not joining anything to watch a video, so perhaps a clear description of the problem?

What amp model and can you link a schematic for it?

What are switching resistors?

If you think the bias supply has cap issues, then measure the ripple on the supply.

I assume you are hearing octave overtones maybe?
That is usually caused by bad filter caps in the high voltage.
