[R-390] R-390 plug-in caps and underside Photo(s) needed

[GENE BALINSKI]

All,

   My R-390 (not A) has developed a minor case of the hums.  So I thought that I would start by replacing the 2 plug-in caps in the audio section.   I am not overly familiar with the 390, and have been unable to locate the plug-in caps.  Could someone please tell me where I could find them ? 

   Also, there may have been some mods by the previous owner(s).   Could someone please point me to a web side with some good top and bottom photos of the 390 (non-A) ?    If not, does anyone have some photos that they could send ?
