The PDF copy was immediately available on download after the payment. However, I noticed that the document was in German, and Ihad to contact a German translator to get it translated it to English. The quality of document is legible can be used for my purpose.

The manual was complete and of great quality. Originally a tri-lingual file, I first received only one language. After a note to owners-manuals.com, I quickly received the remaining languages... Great service, definitely worth it.

Thank you for providing this manual and at low cost.
The Philips scope is of excellent quality, longevity and build and had a couple of faults
when it was passed to me. Having the CCT diagrams is a blessing.
I have fixed the problems and also modded the scope to my requirements.
I have built a 24v Li-Ion pack for portable use from old but good laptop batts.
it is working beautifully and I am well pleased. Keep up the good work Guys.

Awesome quality manual. You really saved my bacon with this one. Was looking for some specific information with regards to my "new" vintage VCR that didn't come with the owners manual. This site is truely a goldmine of available manuals. The quality of the scans are top notch.
Thank-you so much for this awesome manual. If you're looking for this Sony SL-HF400 owners manual, this is the one you NEED to buy. Definitely worth the money.
