The 6Z7 is an unusual double triode. It is designed as a Class B push pull audio amplifier. It operates from low anode voltages as found in universal mains sets and delivers a respectable power of 4 Watts. Rl is 12,000 Ω.The internal structure is obscured by the internal metalising. What can be seen are two anode cylinders of about 6 mm diameter. These are formed of sheet metal and are carbonized.The classic envelope is 37 mm in diameter and, excluding the IO base pins, is 85 mm tall.References: Data-sheet & 1043. Type 6Z7 was first introduced in 1938. See also 1938 adverts. |
