Single Ended Triodes (SETs), the ultimate tube lovers dream.

Forgot to mention that beam output tubes almost always have beam plates connected to the cathodes internally, so you cannot change this. But obviously, obviously, if the suppressor grid (or if there is a beam power tube out there) is not connected to the cathode, it may be connected to the plate. Gotta cover all the bases or someone will correct you. Anyway, if the screen is connected to the plate, the plate family of curves and other curves will look like a triode. The majority of the plate current will flow to the plate though with a little to the screen. What protects the screen is that when the current is maximum, the screen/plate voltage is generally minimum. This of course is not necessarily the case in Radio frequency work. Especially as the R.F. frequency is increased. Then transit times and the simple distance difference between cathode and screen and plate make a difference. Many of the larger older type audio/RF tubes are only good to, say, 15 megacycles on up. It depends on the structure of the tube, internal lead dia., length, capacity etc.
