Schematic question - what this cap is for ?

Hi, tube folks,

Anyone can tell me what this cap is for - marked with red circle, C2, 0.01 uF, connected between BIAS supply and cathode of 2nd output tube?

It doesn't seem to be for high-frequency cut off or RF suppression.

This is Sansui AU-111 schematic.

Thanks in advance for any suggestion(s).
