[Class 38 (iv)] [See also Group XL] A Braun tube, more particularly a television receiving-tube, the positive anode potential of which is earthed, is provided with means for safeguarding the space between control electrode and cathode against excess potentials. A television receiving arrangement is shown in which the cathode 1 is raised to a negative potential of approximately 2000 volts against earth and the control electrode 2 to a potential which, as compared to the cathode, is more negative to the extent of approximately 10 volts. The electrode 2 is biassed through a resistance 3 and is fed with the control currents through a condenser 4, one electrode of which is earthed through the amplifier 5 of small internal resistance. In order to protect the space between the cathode 1 and electrode 2, a glow lamp 6 having a small ignition potential is connected therebetween with a large condenser 9 arranged as shown. A tapping is also taken to the resistance 10 so that the lamp 6 is shortly about to ignite. With a suitable selection of the ignition potential, however, the tapping may be connected directly to the negative terminal of the anode potential source in which case the condenser 9 may be dispensed with. If desired, a resistance 7, large as compared with that of the lamp 6 when ignited but small as compared with the capacitative apparent resistance of the electrode 2 with respect to the cathode, may be inserted in the line 8 as shown so as to avoid a cutting off of any part of the frequency band.
