Grace Towers - 05/22/2008

Very nice clear manual with specifications, exploded views and schematics, been searching for one of these for years. Thanks.

Very nice clear manual with specifications, thanks!

Henry Seiden - 02/26/2009

I downloaded this product and looked through it quickly with Adobe Reader v9. It is clean and a good copy. Some scanned pages are not perfectly square, but that is a minor complaint. The document schematics and board diagrams are easy to read, of good contrast. The whole file downloaded quickly. This is a good service! Sony charges about $100 for the printed version of the same manual. It is still available through their print-on-demand pro parts system, but why would you do that?
