Hi All,
Looking for some guidance and an issue I am having with my Sansui g6000.
I have been using the aux and tuner on it for some time and wanted to run my turntable through it. Noticed that the right phono channel was out at both phono-1 and -2. Read up to find out that there are some troublesome fusible resistors on the equalizer board. Sure enough one was open and the other measured extremely high. Replaced all four and phono channels were fixed.
While I had the unit open, I also noticed that the large caps on the F-2856 driver board were secured with brown glue and that the four nearest 150 ohm resistors (R35/R38/R40/R44) were partially coated with glue and all showed corrosion on the legs. I replaced the resistors after scraping back the some of the glue. I also wiped the back of the board with acetone to remove some extra rosin.
After reinstalling the board, it sounded like there was some distortion in both channels. Did DC adjustments on right channel and left channel but weirdly the only the right channel was adjustable; the left channel only read zero. Playing the tuner and aux only had sound coming out of the right side.
Does anyone have any suggestions for what I should look at next? I'm surprised that a like for like swap of resistors would cause trouble. The old ones were reading 149 ohms while the new were reading 147ohm.
Thank you in advance!
