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.

I was thinking I will never find this manual. User-Manuals had saved my Teac V-7010 which is full of specific functions. Superfast service, excellent document. Thank you very much!
