Well...

Klystrons (like most any amplifier) can be either oscillators or 
amplifiers, depending on the circuit it's in.

I can't imagine Klystron being adapted to work at lower frequencies than 
it's design frequency, except maybe if you use the control grid (if it 
has one) to turn the beam on and off, and use it as a "real low 
frequency" switch.

You could also use them as doorstops, which is "another use", after all.
