There's a DC balance
preset in the differntiator stage. What's the proceue for adjusting it?
From the MC3470 data sheet in the 1990 Motorola Linear

Integrated Circuits databook:
"The potentiometer across the differentiator components is adjusted
until a symmetrical digital output cycle is obtained at Pin 10 for a
sinusoidal input with the minimum anticipated Ep(omega) product."
