The 6BE6 is a heptode or pentagrid valve. The heptode is classically used as a frequency changer in a superhet receiver.Radio and Television both use the superhet principle. To change frequency the incoming signal is mixed with a local oscillator. The electron stream is effectively switched on and off by the oscillator. In practice the process is one of producing sum and difference frequencies via a non linear response rather than just mixing of two signals linearly.To prevent the oscillator and the signal interfering in unplanned ways a screening grid keeps the circuits apart.![](../pics/aaq0597a.jpg)
The solid anode obscures most of the inner detail. At the base the second grid support can be seen to be plain without notches, this is because it is just a pair or rods to act as the oscillator triode anode.The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 45 mm tall.References: Data-sheet & 1040. Type 6BE6 was first introduced in 1950. See also 1950 adverts. |
