The television receiver Modell 36 of the Lorenz A.G. is part of the collection of the Deutsches Museum since 1937. Only a few of this kind have been preserved; so far no other model with an outside-coating of the cathode ray tube is known. In the last decades the coatings of the cathode ray tube and electron tubes started to decay. At the beginning of this work, almost the entire coating of the cathode ray tube is lost. Besides clearing the historical backround the main topic of this paper is analyzing the materials used for the coatings and creating a concept of conserving them.
