With the same scope settings, post the waveforms on pins 5 and 7 (with no input signal).
I'm assuming that the FETs are in the circuit.

it does not change, remember we remove the j112 and join pins 1 and 2 of CA5470, does not affect SE2?
I have installed the j112 and separate pins 1 and 2 of the ca5470, if I have variation in pin 7 of the HIP4080
Adjust SE2 to get pins 6 and 7 as close in DC voltage as possible.
What is the voltage on 6 and 7?
Does that give you oscillation on terminal 5 of the 4080?
