Farfisa Compact Deluxe: 2nd octave with 16' not working

[Guest]

Hi everyone

I got a Farfisa Compact Deluxe today and when I was playing it, I realised that the 2nd octave from the top was not working when 16' tone stops were engaged. Below and above they sound normally, but in the 2nd octave there is no sound. 8', 4' 2-2/3 are all working normally.
What could that be? And can I do something about it?

Thanks a lot for your help!

You've either got a disconnected wire, or a bad solder joint on the control panel somewhere. Check all of those connections. The wire is very fine and easily broken at the solder joint.
