Most of my experiments were deriving typical linear and CRT circuit bias from 12V supplies so I could run home brew designs off grid (ie ground referenced -15v, +15v, 5v, 200v, +2kv, -2kv). Managed to destroy about about 25 quids worth of coil formers learning about oscillator stalling  |
I designed a switching supply many years ago for an automotive smoke meter. There was a need for a high current LT AC supply for use elsewhere, so it made sense to use that for the regulator I/P as well - It makes things loads easier when you are a neophyte power supply designer not having to switch HV and to actually fix the things in a Production environment.
