Hal noticed the same problem in Wurlitzers that are 20+ years old. The problem, in Hal's experience, was that the ribs which support the soundboard (giving it its 'crown') are not embedded in the case; they are simply slapped onto the back of the soundboard. After time, because there is no additional reinforcement from the case, the wood of the ribs and soundboard simply 'gives out' and the downbearing on the bridges flatten the soundboard. Ergo, the whole danged thing goes flat. So, check the ribs and see if in fact they are just slapped on the soundboard. If so, then that's probably why the thing has started to go flat in odd places. How do you fix it? Don't ask me. I'm just an apprentice and have enough trouble setting a concert temperament. Of course, I don't have any flashing lights to help me out so it's taking me a little longer to learn. Then again, I hope to be a better tuner for it, neh? If you've any questions about possible repairs, you can E-mail my boss directly. Cheers! Scott Pickett Philosopher, Projectionist & Apprentice Piano Tech.
