		Cut the track leading to the negative bias generator, insert a 47 ohm resistor.
Between Vin+ and Gnd of the negative bias generator, solder on a 100uF capacitor.
Job done.
Oddly, putting a 560uH inductor instead of the 47 ohm resistor made it worse.

There, I knew you were all waiting with bated breath.
