The bad news is, if you have more than one bad divider for a given note, you can't test the lower ones until you get the ones above it working.Each divider circuit is a small collection of components on the generator board.If you think you've found a bad divider, play the lower octaves of the same note - if they fail, then it's likely a bad divider.If they play properly, then you've got a bad key contact for that particular note.The Oscillator circuit is usually a small collection of components near the tuning coil on the generator board for that note.Oscillator problems can be a bad transistor or capacitor, a loose connection, or, in rare cases, a bad tuning coil.The first octave below the top octave (with the highest even footage on) is the first divider, the next lowest octave is the 2nd, and so on.

It could even be a bad resistor, but that would be rare. As noted above, a bad key contact in the top octave displays the same symptoms as a bad oscillator circuit.Bad dividers are easily overlooked when testing, because if you have more than a few footages selected, they can be masked, or it will seem as though some notes just sound a little "off".
