Hi, I have a Sansui 9090 DB, a Sansui AU 777and B&W DM 5 speakers. The AU 777 was the first solid state amp made,in '68 and the other two were about '78. I have seen the ads lately for gold fuses at $20 apiece. Too cheap for that, but would it make sense to get new fuses in this old equipment? Is there some in between fuse that is better than average, but not $20? Is this just a new way to throw money away? All my equipment seems to work fine.
