    when I switch it off. I guess it has a rechargeable battery somewhere but
    where is it? I don't see it when I lift the upper cover.

    Or, a super-cap. Something like this: https://mm.digikey.com/Volume0/opasdata/d220001/medias/images/928/MFG_FG0V155ZF.jpg

    The schematics are available https://www.thinksrs.com/downloads/pdfs/manuals/SR770m.pdf

    The battery is a BR2/3 2 pin soldered in (page 270 schematic top of page)

    They are fairly obvious usually, seems to be on the cpu board, bottom
    board left side under the psu board

    Thanks. I found a Panasononic BR 2/3 A battery on the bottom board after I unscrewd the top board on the left.
