In a follow-on to a previous conference paper the author explores the use of polymeric positive temperature coefficient(PPTC) protection devices which have an discontinuous I/V curve that is theresult of a physical state change. He gives a simple model for designing networks employing incandescent lamps and PPTC devices together to give linear operation at low levels while providing effective limiting athigher levels to prevent speaker damage. Some discussion of applicationsin current service is provided.
