I have a marantz 2226b and the left channel is low and distorted, I opened it up used some deoxit. Which cleaned up some crackling noise with the knobs. I'm not good when it comes to soldering and all that. I did notice a transistor running hot. It was q746 part number ht318853b0 transistor model 2sc1885 and that transistor is on the main amp and power supply board. I did switch that transistor out with the closest replacement to it, and it still runs hot. Which means something else might be causing it to get hot. I only looked and the service manual to figure some stuff out I don't know much about all the inners of the marantz. Any help would be appreciated.
