My First Post! Need Help On Pioneer SX450

Hello everyone, I’m new to the forum so be kind please. I am trying to work on a pioneer SX 450 receiver that I bought on eBay to help me learn more about repairing vintage stereo. The one that I purchased has a very loud static noise only on the right channel. The volume control has no effect on the noise. The DC offset on that same channel is all over the place as well. One of the problems I’m having is identifying the components on this board. I’ve got a schematic, but none of the component numbers or locations are on the board itself. Any guidance would be much appreciated.
As a side note, it looks like someone that had this receiver before me did some work on the power transistors as I can see that they were all re-soldered but not replaced so I’m guessing they gave up.
