They had also miniaturized the beam pentode vacuum tube.

Graphical Symbol in full simplified diode, indirectly heated duodiode, indirectly heated or triode, indirectly heated or duotriode with separated cathodes, indirectly heated, heating filament with central tapping, internal screening of the system tetrode pentode, suppressor grid connected with cathode triode - pentode triode - heptode (according to the circuit, the systems may be drawn left-and-right reversed) 1.10.

1. Selected Graphical Symbols of Electrotechnology Klaus Janoske 1991

Remember how he went to all the trouble of building a pentode vacuum tube for a job that could have been done by transistors he already had had a chance to get and didn't.

Anything You Can Do ... Randall Garrett 1957

In the final amplifier stage Harry used a Telefunken pentode, the famous and very efficient RL12P35 which was used in the

The Dawn of Amateur Radio in the U.K. and Greece: a personal view Norman F. Joly

In 1935 George and his father Costas built a one-valve transmitter using a type 59 pentode with suppressor grid modulation, and succeeded in contacting most of the world with this QRP rig.

The Dawn of Amateur Radio in the U.K. and Greece: a personal view Norman F. Joly

I ish just a hobbyist~ very pleased with the performance .. running a high gain pentode in triode mode ish welli sweet sounding, almost minimal humming, will eliminate if i load in one or two more chokes but no space riaos~~ good current from transformer coupling .. bass control ish well good and tight~

In triode mode, of course, the screen grids of the KT88 pentode tubes are tied to the plates, and the tubes operate as indirectly heated triodes.

A basic ring-modulation function is also available in the unit -- applying a carrier pitch from an external oscillator to the screen grid of the pentode, this allows making inharmonic sum-and-difference pitch sound effects, with a unique vacuum tube pentode sound.

It uses a 12AF6 / BD6 remote-cutoff pentode and a 12AV7 dual triode.

But ask them to build a push-pull amplifier using pentode vacuum tubes and adjustable gain control and they wouldn't have clue one.
