The PL500 is a purpose designed all glass television line output valve. The American name for line output valves is a sweep tube. The peak anode voltage is quoted as 7,000 Volts and shows why the line output stage of a television receiver was the last consumer electronics product to remain a valve. The CRT excepted of course.TV line output valves found their way into amateur radio transmitters for service at HF (up to 30 MHz) because of their peak voltage characteristics and relatively high current capability.The wide glass tube envelope is 28 mm in diameter and, excluding the B9D base pins, is 90 mm tall.References: Data-sheet & 1040. Type PL500 was first introduced in 1961. See also 1961 adverts. |
