Last week I bought a second hand Panasonic AG-7500 SVHS Hi-Fi Video Cassette Recorder. It is a professional machine with many video and audio options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
