The pictures below show oscilloscope traces for gas mixture 50/50 Ar/CO2, all are shaper output.

new preamp and new cable (baseline adjusted), cosmic rays, 50/50 Ar/CO2, 1900V

old preamp and old cable, cosmic rays, 50/50 Ar/CO2, 1900V

new preamp and old cable, cosmic rays, 50/50 Ar/CO2, 1900V.

The following were obtained with increased anode voltages (and the old cable).
