Comparison old preAmp now(bottom) and 1.5 years ago(top): 90/10 Ar/CO2 - 1450V - fe-55 - full ADC range (ch 4096 = +- 1V)

Conclusion: the old preAmp is fine.

Let compare to the new preamp at full ADC range:

New preAmp Fe-55 90/10 gas, 1450V, full ADC range (ch 4096 = +- 1V)


and at half ADC range:

New preAmp Fe-55 90/10 gas, 1450V, half ADC range (ch 4096 = +- 0.5V)
