Piano, Organ, and Keyboard/F Pedal sound stuck

Question
Thomas when I was given a Thomas Trianon organ that is in good playing condition except for intermittent speaker distortion which I think can be easily corrected by replacing the main speakers.

One problem however is that when I press the pedal tabs, except for the String Bass, the F bass pedal sounds and and sticks disabling my ability to use the pedal board at all.

Help! !

Answer
Hello Craig!  This is the kind of thing that takes some simple investigative work to determine the cause of the problem.  The most likely cause is the F key contact is being held on (closed) for some reason.  Either the contact is broken or the contact linkage is broken, bent or being compromised by something like a paper clip lodged somewhere in the works.  You will need to pull the pedal board out and inspect the F pedal by comparing it to an adjacent pedal.  Hopefully the cause of the problem will be obvious.  If not, you may need to call someone in with some experience.  Feel free to report back any new findings that you discover.  Perhaps we will be able to narrow things down a little further then.
