Thanks for the refresher course. I forgot about the tolerance varyible.Electronic components such as capacitors, resistors and inductors all have a tolerance associated with them, an error band surrounding the part's design value within which the actual value of any given part is guaranteed to lie. For example, the actual value of a 100 Ω, 5% resistor may lie anywhere between 95 Ω and 105 Ω. The actual value of a 1 μF, 20% capacitor may be anything between 0.80 μF and 1.20 μF.
Expecting any two identically-marked capacitors to be exactly the same value is unrealistic. So the fact that your output frequency changed when you replaced one 1 μF capacitor with another 1 μF capacitor is hardly a head-scratcher.
