I would say the 2M2 is there just to shunt the other end of the cap to ground when the opto is off. You don't want them hanging free acting as radio receivers in a high gain amp as this.
It's large enough not to keep the load at about 330k, but still shunts the cap when the opto is off.
Could also be that the opto is physically far away from the tube and c10. more reason for shunting.
