ABSTRACT : A theo-
retical analysis and experimental results are given on compensating the tem-"
pcrature dependence of tt~e working volta,ga in a stabilizer g,1ow lamp by
mee~ns of a novel circuit using a thcrmistor. The influence of temperature
hae- been lowered by one order, without t:he use of a thermostatic oven, and
then temperature time constants of the circuit as a Whale have been shorten-
ed. Graphs ar� pr�sented to facilitate the designing of the circuit. Orig� art.
