Field sawtooth wave signal is sent to the N551's (2) feet by the C592, R550, then the signal becomes convex parabolic wave voltage on the pin 7 after limited, amplified, waveform processed by IC, at the same time, the voltage added to an internal inverting op amp input and 8-pin input line frequency sawtooth is operated and approved to drive the pin 5 of to output, then it forms the concave parabolic wave field voltage (amplitude is controlled by the parabolic wave field frequency modulation of the line voltage pulse). This voltage amplified by V551, then the L561 output field parabolic wave voltage.
