This Sony DXA-H2750 combination dual cassette player and power amp has one
channel out on both cassette mechanisms. There was a wiring snafu which caused
this problem. A 3 pin power supply connector was misconnected to a similar 3
pin cassette test point. I've replaced two transistors on the cassette amp
board which has restored system control operation but there is still a dead
channel. Both channels work fine when the cd player is selected. I have no
schematic and Sony no longer has any manuals in stock. Does anyone have any
info on this set or perhaps can i.d. any of the following IC's and their
respective pinouts?
