Hi leestereo, thanks for the respose. got to the bottom of it eventually. i had two local decoupling caps for both the driver and output stages round the wrong way, reversed the polarity on them and and changed two of the fuses on the back and now i have sound on both channels.
however, after some listening sessions the bass and treble and highs are great but the midrange is quite quiet in comparison and vocals just seem a bit dampened and no longer crisp and loud.
i followed your restoration closely and used all the same values of caps that were stated. mainly using nichicon for the power supply, wima and panasonic for the films and panasonic for the other low esr electrolytics. looking by the pictures i pretty much used the same caps.
my follow up question is, what do you think could be causing my lack of midrange and vocals? do you think i have blown something else apart from the fuses with the reversed caps? or am i just hearing what its supposed to be like after recapping? i think not.
i have recapped a sansui 9090 before and just did the caps but used exactly the same values and had terrific results, the thing absolutely sings.(sounds a lot better than the 9500 atm)
where would you start with the lack of midrange issue do you think?
many thanks for your responses in advance.
