I've been wanting to try out fixing up a Sansui for some time, I finally came across one that I liked; missing volume knob, amplifier issues, dead lamps... perfect!
I'll make a new knob in the shop, no sweat. Inside its a little dirty but the left channel has different driver transistors and some scorch marks on the board so definitely some trouble buried in there. The amp circuit is a lot fancier than other units I've worked on, and the absurdly high damping factor of this unit (200) caught my eye.. so we'll see how it goes as I dig in.
1st step is to give the unit a bath & deox the controls. Then evaluate the amp section, check out the damage and see about getting spec power transistors for the right channel- or appropriate upgrades for both channels. As I go in, I'll check capacitors etc and if any are sketchy or have drifted particularly then I'll recap the set.
