What you are all missing with these fuses is that the sound will really be significantly better if you replace a burnt out standard fuse with one of these. The sound will indeed be more impressive. The signal noise ratio may get worse though depending on how you calculate S/N as S and N increase fro= m their zero levels with the old fuse. What I don't understand is why the fuse case shows a parallel diode/cap? -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of IVP Sent: Monday, July 30, 2012 6:10 AM To: Microcontroller discussion list - Public.
