In Reply to: What does "pentode in triode mode" mean posted by Alex on April 15, 2000 at 15:47:03:
The filament is the cathode in a DH (directly heated) triode, while other designs use filaments as "heaters" that are separated from the cathode. In very simplistic terms, the cathode emits electrons which stream to the plate. The audio signal enters via the grid, which is between the cathode and the plate, and the high voltage from the plate takes the signal to the next stage, usually an output transformer for SE triode amps.A pentode has two additional grids that are left unused when they are used in triode mode. Some people refer to this as a "pseudo-triode" mode.
See the article "How a Vacuum Tube Works" in the Asylum FAQ for more information on basic tube technology. It will clear up some of the basic concepts for you.
