A transformer doesn't have separate taps for 9 V AC *AND* regulated 5 V :o) And I did put a fuse in the 9 V AC line in the schematic. Anyway, my schematic was really a quick design, nothing to be proud of, but I am not convinced that it's flawed. And I'm not convinced that the original CBM design wasn't flawed, either. > -----Original Message----- > From: email@example.com > [mailto:firstname.lastname@example.org]On Behalf Of ext > Raymond C.
