What to do with a composite video oscillorscope

[Caravandal]

I am the proud owner of a Tektronix wfm 300a oscillorscope designed for composite video signals, which in this day and age feels fairly useless. Is it possible to convert its frequency bandwidth to go down to audio frequencies (or even multiply the audio signals up to desired bandwidth)

Or if anyone has any other ideas of what I could do with it i'd be very grateful
