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.

Turn this knob clockwise to increase the depth for a thick chorus sound, and counter-clockwise to decrease the depth for a shallow, light chorus sound. 5.Voice Knob Controls the number of chorus voices used. At the knob�s minimum position, only a single chorus voice is present. As the knob is turned clockwise, more voices are brought in. At the maximum position of the Voice knob, 16 voices are heard interacting with one another. 6. Input Jack Connect your instrument to this jack.
