Hello, Thanks for this terrific website and free service. I searched for a manual for "Panasonic SA-CH31", "Panasonic SA-CH-31", "Panasonic SA CH-31" and "Panasonic SACH31" but with no luck! I believe that model number refers to what is described on eBay as a "Panasonic Mini HiFi Stereo System." If you can find a manual for this that would be much appreciated.
