5FP7 project starting with the focusing coil.

Here is a picture taken of the 'ring' the horizontal time base is set for 100uS or 0.1 mS per division so close to 370uS so 2700 Hz.


   


So if I use 3H I work it as approx 1.15 nF stray capacitance, so would need more than 100pF to make any difference?
