Using a pair of coupled LRC cavities we experimentally demonstrate that instabilities and amplification action can be tamed by a spatially inhomogenous gain. Specifically we observe the counter-intuitive phenomenon of stabilization of the system even when the overall gain provided is increased. This behavior is directly related to lasing death via asymmetric pumping, recently proposed in [M. Liertzer \it et al., Phys. Rev. Lett. \bf 108, 173901 (2012)]. The stability analysis of other simple systems reveals the universal nature of the lasing death phenomenon.
