KA-7300, X11-1350-10 corrected Cap list needed

Hey,

So I ordered in the caps needed per the schematic and before they came in I removed the caps from the boards. As compared the pile of removed caps to what I thought was their respective replacements I found many discrepancies. So obviously there had been some changes since the printing of the schematic and I am hoping that someone has a corrected list for the electrolytic caps that they would share?

Thanks,

James
 
Thanks, I did have those noted. The caps that aren't matched are on the control board so I do have the Power Supply, Pre-Amp and Main amp matched up 100%. I spoke with a buddy of mine who has been doing this longer and he said that many times the caps were changed to adjust the speed of the command controls. So I am hopeful that this sounds as good as it did new.

Thanks for getting back to me.

I recently restored a KA-7300 and found that in the 1st release, there were a lot of 3.3M resistors on the Tone Control assy, which probably was the reason that board was revised and sadly, I could not locate a revised schematic. Worse yet, there are a lot of printed resistors on that assy, so one has to be careful not to damage any traces.

Which Tone Control assy version do you have? Can you post photos?

So your friend thinks the KA-7300 is some type of flying saucer??
 
Here is the board the the bass and treble. The board is X11-1350-10 and what I am calling the left side since they used the same number on the board with the loudness Control.

Is this what you are looking for?
