It was so difficult to find this manual on the internet - thanks a lot for making it so easy and simple. Incredibly handy. AND. It looks you make so many people happy for such small money. Good job!

Talk about a lifesaver!!!!!!!!!!!! This schematic will also work for the Radio Shack DX-392. This is the full blown service manual complete with alignment instructions, schematics, and parts lists.

Wow! I thought I wouldn't be able to find manual for such rare equipment like KM2000E. And here it is! Thanks for fast service!

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.
