The 1X2B is an EHT rectifier for television service. The anode voltage quoted is the peak inverse voltage and this is important in a television EHT generator as the waveform is pulsed and not a sine wave.The R12 has a higher specification than the 1X2B and can be used as a direct substitute for the 1X2B.The insulated heater wires are twisted together and threaded into the central cathode tube. The bell anode has a wide separation from the cathode because of the high voltages involved.The thin glass tube envelope is 21 mm in diameter, and excluding the B9A base pins is 62 mm tall.References: Data-sheet & 1040. Type 1X2B was first introduced in 1955. See also 1955 adverts. |
