Thanks for the reply, but again, how did you come up with that? Was it just something you've seen others do? Did you test it out with an oscilloscope or other equipment? I'd like to know how to make it rather than copying what other people have made. All scenarios are different, so each setup won't be the correct one.

As for the cap sizes, I've read that smaller caps filter out the low frequency noise while larger caps filter out the high frequency noise. How do I see (or hear) this noise? Can it be calculated or does it require machines? Any programs out there that can simulate this?

I'm assuming machines are needed, but is this all done AFTER the circuit is completed? This way, you know what the circuit is generating for noise. It seems logical, but sometimes, there is always a simpler path.

Thanks,
Tony
