![]() ![]() I replaced a few missing screws, touched up the stain on the end panels, vacuumed the inside, cleaned the outside, and let the customer know it was done. It took about twenty minutes, but after that it was all working perfectly. ![]() Fortunately, SCI built in a relatively painless procedure for doing this. Since the unit tunes itself, that meant that the main voice board needed to be rescaled. Two of the voices were really, really off the oscillators were nowhere near each other in pitch. And it did! The memory must have been hosed from the start, because all the patches sounded fine and the locking up problem went away. One bad thing about this unit is that there’s no indication that it’s receiving, so had to unplug it, schlepp it downstairs, and hook it back up to the amp to see if it worked. I was unable to get the factory preset WAV file to load, so I used MIDI-OX to push the SysEx files over. Replacing the battery, of course, completely wiped out the memory. Although it’s mounted from the top, I had a holder that was perfect for it. ![]() Since there’s no way to know how long that would continue, however, I went ahead and replaced it. I checked the battery despite it being the original I was still getting the correct voltage. I’ve got keyboard rebuilding down to a (tedious) science. ![]() I was in high school when this rolled off the line. The date of manufacture – 10/19/83 – is clearly visible here. Four screws, fold the control panel up, everything is there in front of you. One of the things I absolutely love about older equipment is how easy a lot of it is to work on. I let the customer know he just said “fix it’. The patches were all really, really wrong, and it would hang up randomly. Testing it, however, showed an additional problem. When it was dropped off, the owner said it had a bunch of non-responsive keys and he wanted to see about getting the battery replaced. ![]()
