No output from left channel on my Pioneer SX434. Well, I got the schematic now. On the AWK-034 (power amp section) I replaced Q16 (2SC1318), Q20 (2SD131) and Q22 (2SB507) - all transistors went short - as well as R73 (18ohm 1/2W) - burnt out. But still no output.
Am I missing something? Any ideas?

Just finished checking. R83 / R85 and R79 / R81 are fine. 2 pins on Q16 were inverted (wonder how it could have happened???).
But still no sound on the left channel. Now I've got a very loud hum.
