Build a +/- 15V Power Supply

I build a dual-rail 15V power supply to power the RIAA pre-amp I need to build for the jukebox. This is a handy project build anyone can tackle that is really useful when playing with audio circuits. I've left all my screwups in, so you can see what not to do! 😂 Also, I mention a datasheet-recommended decoupling cap. I had a read of the datasheets and can't find any reference whatsoever to that cap - so it might just be popular myth... but I'm leaving it in.
