To check an oscillator I use an item of instrumentation which few to none of you would own - a Tektronix P6022 current probe. Probing a terminal on an oscillator coil with an oscilloscope probe could disturb the operation of the oscillator. Because of its design clipping the P6022 probe onto a coil lead will cause less disturbance to the oscillator circuit while providing a sample to my 'scope.
