Pentodes and Tetrodes can have their screen grid fed from a percentage of the primary voltage on the output transformer, giving efficiency and distortion that is a good compromise between triode ( or Triode-strapped ) power amplifiers circuits and conventional pentode or tetrode output circuits where the screen is fed from a relatively constant voltage source.

The EL34, 6CL6, 6F6, 6G6 and 6K6GT are some examples of true " screen pentodes " used for power amplification, using a screen for the suppressor grid, rather than the higher efficiency, lower distortion beam forming plates used in " Beam Pentodes ".

Pentodes are made in two classes: those with the suppressor grid wired internally to the cathode ( e. g. EL84 / 6BQ5 ) and those with the suppressor grid wired to a separate pin for user access ( e. g. 803, 837 ).

* Pentodes are almost unaffected by changes in supply voltage, and can thus operate with more poorly stabilized supplies than triodes.

* Pentodes ( and tetrodes ) tend to have a much lower feedback capacitance, due to the screening effect of the second grid.

* Pentodes and triodes ( and tetrodes ) do have essentially similar relationships between grid ( one ) input voltage and anode output current when the anode voltage is held constant, i. e. close to a square-law relationship.

* Power output pentodes, also referred to as " Beam Pentodes ", include the Sylvania ( and possibly GE ) 6CA7 version of EL34, 6V6GT and the EL84 / 6BQ5.

Pentodes, therefore, can have higher current outputs and a wider output voltage swing ; the anode / plate can even be at a lower voltage than the screen grid yet still amplify well.

It would challenge sharply not the cult of the motor car itself but some of its ancillary beliefs and practices -- for instance, the doctrine that the fulfillment of life consists in proceeding from hither to yon, not for any advantage to be gained by arrival but merely to avoid the cardinal sin of stasis, or, as it is generally termed, staying put.
