Essential for popping the top open and cleaning and replacing what needs repalced. One note: the Ornamental Panel is attached with some adhesive as well as screws and faders so don't be shy about prying it open.

Thanks for manual for Luxman M02. I'll recomend this site to my friends for sure! Keep on the good work!

Nice, really nice. I was happy to receive manual in true electronic form, instead of scanned original. This manual includes: Wiring diagram, circuit diagram, block diagram, PC board, adjustment, exploded view, PARTS CATALOG and more.. It's full color manual, not B&W or grayscale :)
