Johannus Organ Opus 240

Got it in 2006. It never functioned well. I got an electric scheme from the factory. Had to give it good maintenaince. All the manuals contacts had to be cleaned, the contacts of the stops, replacement of some IC's, removing superfluous soldering at one spot where the tones sounded wrong, cleaning the the magnetic switches of the headphone/speakers, tuning at 440 Hz, adjusting the volume of groups of stops, tuning the 1 3/5 stop.

You dont need that much knowledge of electronics, some basics, an electric scheme and logics is enough.

It sounds like it has never done before. The work is finished on january 23, 2011. It took me 1 week to find all the problems and solve em. Some IC's that are hard to get were available at Ebay.

Now I can make new movies.
