   True!   And it is a shame that they aren't!

   If the DAF is built per the original design, with a time constant in
the screen circuit that will allow the screen voltage to follow the
envelope of the SSB signal, then a two-tone test will give valid results.
 
   If the screen voltage TC has been modified, such that a constant
screen voltage is seen with a two-tone signal, then you no longer have a
DAF amplifier.
