Hey Skipp, I've just removed the AC supply from a SpectraTac receiver shelf. Has a Micor RX & a couple of cards. System draws less than 200ma.
I used an LM317 (a couple of caps & R's)... soldered the tab directly to a piece of PCB material. Runs all day long with 12 input & doesn't even get warm. - Using it for a solar 6 mtr RX site. Tim W5FN
