Not a clue. I don't have a 500. But, the 400 filter uses that board.
Look for a 15K resistor connected to the top of the Q slider.
That 15K resistor connects to the input of a 748 quad op amp, two 100K resistors and a 3.3pF cap.
The 100K resistor in parallel with the 3.3pF cap is the feedback limiting resistor from the LP output back to the network input.
Reduce the 100K.
