Yes, I believe you are right... It has a proprietary AC power jack (grounded) and a typical DC plug in jack.. You can even run it off your car cigarette receptacle.. So it accepts bog standard 12v DC supplies.. It is a Technics SL-10.... I could use a DC wallwart but, I was thinking of a more "audiophile" (cleaner) type power supply.. I just ran across the Tripp lite product talking about "clean, pure DC) and I thought that may be a cheap solution just to try. I would think it has to be better than running AC directly from the wall like I always have.... I was wondering if the 13.8 V rating that the tripp lite product said may be too much or NOT matter...
