CR-1020 capacitor parts list?

I just received a nice CR-1020. It's working, looks great and sounds pretty good, but I would like to re-cap it as I know many of those old parts need replacement. I'm pretty handy with a soldering iron and have successfully rebuilt several Marantz, Pioneer and Kenwood units. They all sound, look and work great.

I've been looking through the service manual I downloaded from HiFi Engine, and while I do see a "Parts List" section at the end of the document, there are only a handful of electrolytic caps listed. Certainly not enough for the entire receiver.

How are people generating lists of capacitors for these receivers? I've tried going through the service manual schematics and writing down all of the electrolytic cap values down but the schematic scan isn't the best and there are many that I can't read. Am I really going to have to open the receiver and go through each board part by part to build a list of caps? I've searched here on AK and have found nothing usable so far. Maybe I'm missing something?

Any suggestions and/or help would be greatly appreciated. Thanks!

Yep, thats how I do it. I open the unit and go through every board . Many schematics are labeled wrong
and sometimes the parts list.

Also there are known mistakes on the schematic and board layouts in the service manual for that unit.

But it's worth it to take the time and do the research. Also look at the thread in the solid state forum that deals with bad transistors as you might as well change those out while in there.

Precisely. Not only that, but you will get to see the correct parts in YOUR unit. In many products case, (and not just Yamaha), components are updated throughout the production run and rarely ever get updated schematics, service manuals or field notes to document these changes. So going through and seeing what you actually have will be the most correct for your unit. No doubt you will find discrepancies and silkscreen errors compared to the service manual and schematics. Always default to what is in your unit and has been working for the last few decades. Of course this only applies to something that hasn't been monkeyed with by well intentioned people who don't know what they are doing.
