I have had my Casio CT6500 Keyboard from new., purchasing it around April 1986 from Bay Music in Herne Bay, Kent. They had just been over to Frankfurt, Germany and brought one back with them to sell from in their shop. I love just about everything Casio and Yamaha and I was definately up to buy it. My wife stored my keyboard away (against my wishes) and it appeared to have become damaged as it just gave up the ghost. However, about a month ago, I teased it out and stripped it down, taking great care with the single layer mica boards. I wanted to clean the sliding controls as a starting point. It was when it was in bits having removed several boards to get at the topmost boards, that I discovered that Casio used professional sliders on the keyboard and the keyboard just did not require being dismantled to clean the sliders, merely sprayed with Servisol switch cleaner from the playing surface just as though I was working a studio mixing desk. Well, I managed to put my keyboard back together again and it works a treat, just like new. No screws or parts left over, no broken cabling. However, if you do need to take any Casio CT6500 keyboard apart, I would suggest that you first place it on a low surface like a "Long John Coffee Table". Make sure that you cover the table in a soft table cloth and work by removing all of the self tapping plastic screws from underneath beginning around the edges of the keyboard and working inwards. Very carefully seperate the case top from bottom etc, and open it up, propping up the top by using several stacks of old VHS videos as their size is convenient in "layering" (raising) up and down the seperate component parts of the case which will prevent the very delicate "RIBBON CABLES" from being pulled apart and/or becoming damaged. It's very easy to slide in or out a single VHS Video to keep the component parts weighted and angled for "best practice" etc. By doing this, I was able to work completely on my own. I learned this lesson from several years agao, when I had to take the case apart as I presumed an internal fuse had apparently blown. When I got the two halves of the case apart, I discovered to my horror that the ribbon cables were all slding undone. Casio did not place long Ribbon Cables in the units that locked in position as we see on later electronic devices etc. All of the ribbon cables are too short to make it safe for just one person to work on the keyboards. I had to call out for my wife to come and help hold the case close enough together for me to rejoin/locate the loose ribbon cables. It was a "NIGHTMARE". Somehow we managed it between us, but never again, it was like trying to teach your wife how to drive your pride and joy (car). Very sensitive to every detail of your manerism if you know what I mean ...! Believe me, it is far better to work alone - hence the VHS Video cases, they don't talk back to you when you are trying to concentrate. Make sure that you have all of your tools close to hand, and I mean within "ARMS REACH", BECAUSE YOU ARE GOING TO NEED TO HOLD THE COMPONENTS TOGETHER UNTIL YOU'VE SKETCHED THEIR LAYOUT AND THE "INTERNAL POWER CIRCUIT-BOARD" HAS THE SHORTEST CABLE YOU COULD THINK OF. WHY DIDN'T CASIO USE LONGER CABLES AND PLACE LOCKS AT EACH END OF THE CABLES ? Right, well, you've heard it from a Computer Engineer from the "Old School", from the period when engineers really had to wire up and plug in computer chips not just change boards. Too many occasions we had to make up our own mods ... WIRE LINKS to join circuit boards together. The Casio CT6500 is from that period. The electronic circuitry is very basic, but excellant - producing top quality sampled sounds. Great musicians swear by VOX VALVE AMPS and they are DEFINITELY NOT WRONG. No-one can better the sound quality of VALVE/TUBE AMPS, "DITTO TO CASIO AND THIS VERY OLD TECHNOLOGY AND CIRCUITRY" WHICH STILL PRODUCES TOP QUALITY SAMPLED SOUND AND PLAYS AND PRODUCES WHAT THE MUSICIAN TRULY WANTS TO PRODUCE. YES WE CAN ALL DO WITH A FEW MORE GIZMOS, I NEARLY SAID BELLS AND WHISTLES ... WHICH WE DON'T WANT DO WE. MUSIC IS MEANT TO BE PLAYED AND ENJOYED BY THOSE PLAYING IT AND THOSE LISTENING TO IT. I REALLY DO NOT EVER WANT TO BE APART FROM MY "CASIO CT6500 KEYBOARD".
