When attempting to restore my old JVC AL-A1 turntable, I found the manual. Since I thought it might be useful to others, I’ve scanned it and you may freely download it here:
Manual for: JVC AL-A10BK AL-A1BK AL-A1BKX
Document was scanned using Goodnotes for iOS. It’s searchable and the text is selectable, but I don’t know how well the non-English language text scanning went.
