Характеристики Радиолампа 12BE6 75U43 RSD
The 12BE6 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 rather than just mixing of two signals.
