I am looking for a german language original (if it exists) of the english version of Telefunken's 1960s application note for its voltage stabiliser tubes. The english version (here: https://tubedata.altanatubes.com.br/other/Telefunken/Telefunken_NewVoltageStabilisers_1966.pdf) leaves a bit to be desired and I'd like to work from the german original, if it exists and if anyone has a copy to hand.
"In such cases the circuit capacitance must be rated so much lower the further the static characteristic shall be measured free of oscillations in the sub-
normal region towards lower currents because both the inductive and negative real components of the track conductance are approximately proportional to the direct current flowing in the circuit."
I see what you mean. It even begins the next sentence with "Obviously"!
