Vintage Synth Repair

Thank you all very much for taking time to respond.
I checked all the plastic sticks that activate the contacts, they are 
all in place. I cleaned the contacts with non-lubricating cleaner and 
a piece of heavy paper soaked in cleaner to make sure the conacts 
were clean. I traced the wires through the organ and could see no 
obvious signs of damage anywhere. The F pedal plays an E note; I 
tried putting a piece of paper between the contacts of the E 
pedal...the F pedal still plays an E.
Any more suggestions?

Bob
