A second series of monolithic preamplifiers based on epitaxial channel JFETs and intended for calorimetry at hadron colliders has been realized. The employed buried layer process has been upgraded, resulting in a lower pinch-off voltage and a reduced power dissipation. Results will be presented on noise, dynamic behavior and radiation damage. New versions of the preamplifier have been designed for both large capacitance detectors and for low capacitance pre-shower detectors.
