1x GP-5 glass-envelope beam power triode Transmitting Tube = GP5 ED500 6BK4 ??-5 Description The Svetlana GP-5 (??-5) is a glass-envelope beam power triode intended for use as a shunt regulator or pulse modulator in high-voltage systems. It features anode operating voltage of 30 kV and a plate dissipation of 37.5 watts. Originally intended for color-TV voltage stabilization, the GP-5 is similar to the Telefunken ED500 and may be used to retrofit equipment which uses the American type 6BK4 or other high-voltage beam triodes. Near equivalent: ED500 and 6BK4. The tube is manufactured by the Svetlana, St. Peterburg, Russia.
