Application Notes
The VP.22 is a variable-mu screened Pentode for use as an H.F. amplifier in battery operated receivers. It is preferable to connect the screen to the full H.T. voltage through a series dropping resistance. Suppressor grid should be connected to earth or potential negative to earth.
