hey guys, I've got an old Sansui AU-505 that was my grandfather's. Audiologically speaking, it's not sounding so hot. One channel crackles (right), it seems to be fuzzy until I crank it and then it "connects" better but it is generally sounding a bit distorted on the top and bottom end in BOTH channels. It does get good and loud. It's just not "clean" at any volume level. My first thought is that maybe I need a Marantz 1060, but then I had another thought. Maybe I can rebuild this? Especially for less than a Marantz maybe? I found this excellent thread: http://audiokarma.org/forums/index.php?threads/sansui-au-505-rebuild.598808/ I have a few questions: - Should I do this rebuild myself? - If not, how much does a rebuild run? - Should I use parts of identical values? (thinking from DigiKey maybe?) - Should I upgrade any parts while I'm in there? (Bigger caps, higher quality resistors? What brands should I use? I'm not against using quality.) - WHAT exactly should I be replacing? Is there a guide I should follow? - I will clean or replace the pots per your advice. Qualifiers: I can solder. I've built my own guitar pedals before, though it's been a few years--so I AM familiar with DC circuits and such to a small degree. I've popped the hood off on this and had a look-see before. I'm only afraid of zapping myself off the bigger caps, or of destroying it, since it was Grandpa's. Thoughts?
