Piano, Organ, and Keyboard/organ issue

Question
Hi, I have a wurlitzer total tone custom organ, model 575. I got it from some people who said it worked, but had it ready to move when I got there. When I got it home it did not work. Its very heavy and Im so discouraged but dont know what to do with it now. Id love to fix it but have no idea what to do. All I can say is this, that it seems to have two big bellow things in it that spin, lot of transistors. When I turn it on you get fuzz and crackle and some of the keys will make distorted sounds for a short time but then it fades to where they make none. from the time you start it it makes a buzzing hum sound and it sounds like one of those spinning things is...idk you can hear it spinning like  its off its axle. Again, most of the keys will play, not clear but barely then after 30 seconds or so no key does anything except make the same horible noise like a blend of buzzer/horn whistle...lol idk...any clues? something simple? its a nice piece of furniture, sure its worth something in its day, and I really want to make it work for my daughter...thanks JT

Answer
Hello Joseph!  According to my records, the 575 is a 1977 spinet organ dubbed "The Funmaker Custom with Orbit".  If this is indeed what you have then I know what we're speaking about.  This instrument is an IC divider organ which probably uses a top octave synthesizer chip as the sound source.  These chips are very difficult to locate now days.  Also, the spinning device you mention is a Leslie-like device used to create a tremulant effect by rapidly reflecting the sound around the room.

Organs of this age commonly have problems with contacts and electrolytic capacitors in the power supply and amplifiers.  Because these instruments are quite complicated, you really need an organ technician who is familiar with these instruments to perform an evaluation.  The problem with this endeavor is it is common for repairs to quickly exceed the value of the instrument.

Assuming the instrument did in fact work before it was moved, there is a chance the problem(s) you describe are from connectors which are making poor contact.  This can usually be corrected by systematically disconnecting and reconnecting the connectors.
