This is a typical coupling capacitor used between stages. It's the AC signal
path from the output (plate) of a previous stage, to the input (grid) of the
following stage. Not all configurations are the same, it is easiest to spot if
you are following the AC signal path, as a job of the coupling capacitor, is to
pass the amplified signal to the next stage, but block the DC voltage from the
plate, or collector circuit if it's a transistor amplifier. And again some configurations
will be different.

In the IF sections of your tv coupling between stages is done with a coupling transformer,
there is a load resistor after the transformer, but the transformer passes only the changing
signal amplitude from one side, to the other side, so again DC is blocked.
