I suspect all of us have become frustrated with some project at one time or another, I know I have. Stay patient and be persistent. All will eventually come together, and later you will look back and chuckle to yourself about the whole thing.
At least I'm learning a whole bunch It's also deeply encouraging to find that there are still places on the internet where people are nice and helpful.
Just an update, I've got it all working now. The PSU i built works fine and was simple enough! Almost no noise what so ever so I'm a happy camper Thanks all for your help!
