Vintage Synth Repair

Hi folks nubie here our church organ a Wurlitzer M# c. 125 S#100102, will on it own some of the time make a sound almost as if the organist was pressing a key. Haven't found anyone in our area that knowes anything about organs. Hoping that someone on this board might pass on some information on what is causing this and how to cure it. Thanks in advance for help.

I've worked on a whole lot of organs over the years...

When you said Wurlitzer one thing came to mind immediately.  Look for hardware 
to open the thing up,  and swing the keyboards up.  Usually there's a metal 
stud or similar at each end that when removed allows this.

Wurlitzer used key wires with plastic spacers in between them,  multiple wires 
per key.  On a number of the ones that I've seen the plastic has fractured,  
allowing the wires to get into positions that they're not supposed to be in.  
If you note specifically which keys seem to be the ones with the problem,  
and then look at the contacts under them once you swing the keyboards up,  
you should be able to tell whether that's the issue or not.

If it is,  then maybe you can still get the required assembly from them (I 
haven't tried for many years now) or rig something.  If on the other hand the 
problem is not immediately apparent as a mechancal issue,  then you'll be 
looking at some other cause,  a problem in a keyer circuit or similar,  and 
the solution to that one depends on the exact model.

Thanks for the information Roy that gives a starting place, will let you know what I find.

Hi Tim Thanks for the reply, we are in southwest central AR. May give the guy in Greenbriar a call he a little less than a100 mi away. Do you know where I might find books on servicing this organ.
Thanks Harold
