Hiyas,
You'll get a ton of feedback in DIY...I will say that ceramic is not likely your best option in C3...A wima or poly would be better and smoother to my knowledge....Having said that, it has much more to do with the value you select and the variance of the type of cap you use...Some can swing wildly in their values giving different results each time...Ceramic are known for having wide variances...
Don't quote my terminology BTW...Just offering what I know...
Cheers,
Fig
