Last summer I made a service call on a Samick 172 grand piano with a model 32 Piano Disc system. The problem was they had bent the slider on one disk and worn out a couple of other disks. This system has always had a problem being too loud so the original installer covered the bottom of the case with masonite. There is almost no air circulation in the area of the transformer and sustain solenoid and there is a fan on the sustain solenoid. This piano was in the dealers show room for a couple of years and went out as a rental several times. It was sold to a large group clinic for there reception area about 5 years ago. This is a 3 story open lobby. The piano plays a lot. They keep the lid closed and locked. I did not see any sound board problems. An interesting side note. The original plans called for the piano to be suspended by cables at about a 30 degree tilt so that the key bed was at eye level of the second floor balcony. How many tuners carry their own scaffolding? The dealer convinced them the piano belonged on the floor. John Dewey
