We analyze the current through a small NSS-transistor due to Andreev reflections in the NS-junction with respect to finite temperatures and the electromagnetic environment of the transistor. We show that a typical low-impedance environment strongly modifies the nonlinear I-V characteristics measured by the differential conductance .
