Default one half of a tube in schematic????

What is meant when a tube amplifier schematic has one half of a tube in the layout. I know there are many dual element tubes but I am missing something here. Is this like a dual jfet?

Very much like a dual JFET. There are lots of types that include two triodes in one bottle (6SN7, 6SL7, the entire 12A*7 family). You also have types that share common elements (6J6, 6SC7 -- share common cathodes for LTP use).

You also have mixed types (pentode and triode in same bottle: 6KE8 (independent elements) 6X8 (shared cathodes)) mixed small signal triode + large signal triode, and so on and so forth.

Compactron types can have even more units in the same bottle.

Usually the other half is used somewhere else in the circuit (sometimes other channel).
