have download a number of manuals todate , most are excellant, one or two sometimes a little difficult to read but a least avaialable, great site .
Excellent had everything I wanted, very happy with purchase
This service is relatively cheap, document is fast available, schematic is readable.
So far Iยดm a satisfied customer. I have only downloaded "TECHNICS SX-KN470 Service Manual" maybe I will use it later.
Good manual. It is complete and of high quality, both text and graphics. The schematics are with the original big size, so it can be viewed or printed without any loss of resulution and sharpness.
