You will really enjoy that SX-1500TD once you get it going! I have one also, and used it as a daily driver in my office at my previous job until one of the stereo channels quit working.

Do you have all of the service info for that receiver? If not, I do...just let me know if you want a PDF copy.

I would start by replacing all four of the power supply diodes, as well as all of the electrolytics on the power supply board. As a precaution, check the transistors on the power supply board and the audio output transistors also to make sure they are OK.

Edit: Well, while I was composing my post and looking at the schematic, Mike (Morzh) beat me to the punch and basically said the same thing I did.
