MCM with removed capacitors between DAC and OP, and extra capacitor
between OP and SALTRO.

All plots are with the settings:
polarity = 1
gain = 0 (12 mV/fC)
shaper = 0 (120ns)

nominal reference voltages

decay set to 0.5V (I think, can not measure it).

good pedestals

noisy pedestals

noisy pedestals

The plots ch*.pdf:
individual time sweeps for a few channels and different events 
on chip 0 and chip 7.
all channels are clearly "noisy" with some "regular" pattern(?).

Should try other settings of the chip, but then the usual "hangup" occurred
all the time, after have been running smoothly for 2 hours.

Temperature measured when all on: 55 degrees.
