    I've been listening thesx-828 for a long time
    It is perfect. I have listened for 2 ... 3 hours uninterrupted, and without any problem.

    But, I have to think the phono section of it a little noises ... it is not clear.
    It may be my impression, or I'm strange, since I've been listening my Lps in tube fisher and scott amps ...

    I have found the vinyl sound very bright ... very sharp ... on sx 828
    Maybe it's the caps and transistors I used in....
    I used common EPCOS electrolytic capacitors, and BC 547 series transistors in the phono section, to replace the 2sc458.

    I just changed these components.
    Should I change the capacitors for some better, like panasonic or Nichicon of some specific series? Should I exchange the BC547 for some better less noisy? Wish i upgrade other component?

    I have used Fairchild KSC1845FTA to replace 2sc458 -- they seem to work well. Dan :music:
