eflower I give you a lot of credit for trying. I hope you succeed because frankly, I'd like to know how your switcher performs running off of DC current from the PS1 board.
The original O scalers used converted tinplate equipment, feeding DC to the universal motors thru an outside 3rd rail. A lot of folks claimed improved performance that way. I never tried this but it makes me want to start experimenting myself!
Matt do you think your wiring method might provide better load/speed regulation than ACDX Rob's (which is the accepted norm?)
Good question and good thread!
