Vintage Synth Repair

My mother has a Wurlitzer electronic organ (circa 1970) whoose keys are 
making an extra squeaking or rubbing noise when they are pressed and I 
am wondering what sort of maintenance the organ might require to 
correct this. I hear the squeaking/rubbing when listening to her play 
while I am in the same room and find it most annoying when I make audio 
recordings as my microphones are picking this up as extra noise.

Thanks in advance for any suggestions.

It's probably the return spring on the back of the key. It may need just a
touch of lubrication or reseating in the back of the key. These are
individual keys. If it's the keys that come in octave strips, then that's
another problem. Have never hear of those keys squeaking though. Do you know
the model number of the organ.

There might be some kind of rubber key guide underneath the keys to dampen
the movement of the keys up and down and right to left. I had a similar
thing happen on an odyssey I own.

The model number is #4500. What kind of lubricant should she use? So,  
do the keys just snap off, somewhat like those on a computer keyboard  
or how should we access the springs?

Thanks.

You have to remove the top and possibly the back of the organ then remove
one screw on each side of the stop tab rail and it will pivot up. On each
key is a retaining clip. Carefully pinch the pins together slightly and pull
up on the pin to remove it. Slide the spring off and put a small dab of a
white lubricant in the groove on the back of the key, replace the spring and
the retainer lock. This lock is also how you set the key pressure for each
key. Pushing down farther increases the key pressure and moving it higher on
the pin decreases the pressure. Check the key for proper pressure by
checking the adjacent keys using only minimal pressure. If you needed to
remove the key completely, you have to remove the spacer at the back of the
key and the key then lifts out. Hope this helps.
