PS
I'll try to put together some thoughts on the build for inclusion with this but as you can see it's actually a pretty simple circuit with a low parts count. The only small correction that needs to be done is that the transformer is actually the BFT-1B, they don't make the 1A anymore but they are essentially the same so I'm not going to worry about it for now. And it should go without saying but I'll say it anyway, there are lots of options that individuals can choose. First and foremost the power supply could be something entirely different and might be made simple enough so that the entire thing could fit in one chassis. Along those lines there's nothing forcing anyone to use the giant motor-run caps that I did, the output caps can be whatever your heart/wallet desires. But what's shown is exactly what I built and the results are more than enough to convince me that I made some good choices and that Pete gave some great advice.
