Re: Capacitor Use
That 2(.2) uF capacitor should not connect to rectifier +. The rectifier + should go to a 50uF then via 3.9k to another 50uF and then via 10k to the 2(.2)uF.
Now we know where it is, it is safe to say that it could happily be replaced by the film cap, but equally happily by any electrolytic of adequate working voltage and larger capacitance that would physically fit. In other words, its capacitance isn't critical. 2.2uF was probably the smallest and cheapest value which would give the required performance in the design.
