Vintage Synth Repair

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.

organ - what to do?


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.
