WebbThe first grid (the grid physically closest to the cathode; what in conventional tubing is called the control grid) should be tied to 12V. If you're using a conventional tetrode or pentode in space-charge mode, make sure you put 12V on the control grid, and use the screen grid as the control grid.

There were different market conditions in Europe. In any case, if you were designing a receiver, especially a comms receiver, I think there'd be a lot more to choosing the mixer(s) than looking at the datasheets.

Its primary application is in superheterodyne receivers, where it is used as a combination local oscillator and mixer. In operation, the cathode, control grid, and screen grid are used as the essential elements of a "triode" tube with appropriate components to form an oscillator. therapeutic medicine meaning
