A stubborn audio hum made me rethink how I tighten things.

In my experience, I always figured hand-tight was good enough for avionics rack screws. Last month, a pesky hum in the comms led me to torque them all to the manual's spec, and it cleared right up. That small win showed me the value of following the book, even on what seems like simple stuff. Your mileage may vary, but it's stuck with me.

That audio hum (like my guitar amp) was so puzzling.

Joe traced his amp hum to his fridge cycling on and off.
