Since the Spooky2 Central Beat Frequencies preset uses a wave cycle multiplier of 2, the generator will run at 1/2 the speed of the frequency that is actually being rendered on the plasma tube.
So the above screenshot shows 76000 Hz, which means that the frequency of the tube is 152000 Hz -- well within the limits.
The modulation frequency of 71250 Hz renders as 142500 Hz, which means the original database frequency at the time was 9500 Hz (152000 - 142500) as indicated in the first screenshot.
Using a modulation frequency of 142500 Hz means that the first lower sideband frequency generated will be 9500 Hz, the intent of how this preset works.
