In Reply to: RE: Why wouldn't it be a drop in replacement,.... posted by Lew on October 03, 2016 at 09:00:30
Good reminder Lew. Not a bad idea to do the math on that based on the reg. and input voltage . Forgot about that. I did the math on my project and the Schottky would have been fine. Didn't use one though. Since you like Schottky's better than soft recovery maybe you can suggest what specific device you liked to Sherod in case he wants to do the comparison. It seems to me that an experienced opinion might be better than getting a random device from ebay. I don't think there was a brand listed on the ebay one. Tweaker

to me a Schottky is a Schottky; I've never compared brands. Likewise, for a UF or Stealth type. Funnily enough, the only thing I can say for sure is that I heard a definite difference in favor of Schottky when I replaced IXYS Hexfreds with Schottkys, in both a preamplifier and in amplifiers. Not night and day, but a bit better, less hi-fi-ish, with Schottkys. These observations are so tenuous that I would normally not mention it.
" In the instances I've used schottky instead of soft recovery, the perceived result is a "darker" background and smoother, even slightly rolled-off top. This is very noticeable with power supplies for cd players, where obviously these are pretty positive factors (esp. lack of "digital" signature). Haven't tried the latest technology schottkys, but I expect they will be good too."
I've never bothered to replace rectifiers in an SS device like a CDP. My experience is limited to tube audio. However, if one does such a thing, one ought to be aware that the resulting change in voltage, even though small, may account for the perceived difference in sound.
