The old Galaxy had a 2sc2166 driving two 2sc2312 transistorsThats good to know but oddly I pulled a good set of 2312's and a 1969 was driving them. From a Galaxy 99. I was going to try the known good set in a saturn that was cabbaged with Chinese fakes. What would replace a 2166?
( see schematic below) from the factory, maybe some one swapped a 1969 in to replace the 2166 after they became inobtainum but it really don't belong there.
Yes the very old 1306 and 1307 were driver and final many years ago.
Hugo Semi makes replacement 2312, 2166, and 1969 transistors that's about as close as you are going to get.
I don't trust any foreign sources on e-bay for replacement transistors.
