Can you help me use a 'Scope to find oscillation?

Looking for a patient teacher to walk me through using a 'scope to find an apparent oscillation in a Kenwood KR-5600. I'd love the help if anyone has the time to try!

There is a sudden hum/buzz current draw at the full open position of the Treble control. I'm thinking it could be oscillation. er, no?

Love the help with the 'scope anyway. Thanks!
