Question
I have this Baldwin Overture Fun Machine Organ, same as the one in the picture here:
http://www.nextechclassifieds.com/listings/view/395141/

It works fine, except for one key, which sounds like a duck quacking. It is a terrible noise, and sometimes moves to different keys when I change some settings. Anything I can do myself or do I just have to pay the guy to come look at it? Thanks in advance!

Answer
Hello John!  This organ uses IC divider technology.  If you have only one note that is causing a problem then I can rule out the TOS chip and dividers.  Therefore, the problem is more likely to be in the voicing circuitry.  If you wish to try troubleshooting the organ yourself, I suggest you remove the back of the organ, turn the organ on, have someone hold the noisy note down, and while it is squawking start gently touching the various wires and components in the back of the organ until either the note's tone suddenly improves or you cause a change in the note's character.  I believe this instrument uses styrene capacitors which can become intermittent.  If this is the case, touching a bad capacitor can sometimes cause it to fix itself (although temporarily).  If you do find a loose wire or bad component that suddenly makes the note work correctly, make certain you make a note of its location so a technician can find it quickly should you decide to call one in. Without more specifics this is the best I can offer.
