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.

Just got this Manual downloaded... Scan is PERFECT! This is EXACTLY what I needed. However, please update your site info to state that it may take more than \"a few hours\" to have the download available after payment - - - I had to wait 4 days, in my case. Otherwise, I am very happy with this!!! Thanks! --- User-Manuals.COM comment We\'re sorry for delay, we had major problem with our download server, but all is ok now and downloads works as previous.
