Kon,
   As we all know sound is what you like. That being said::::::
The '66 does NOT produce a distorted sine wave sound. The X produces sine
waves that the original design only promised. Throw a scope on both and see.
The filtering on the X is low pass, band pass and high pass depending on
frequency group. It does not sound like other electronic organs. The '66 has
true sinewaves. It also generates square and sawtooth for other voicings in
the unit. Add a 122 or 770 and you will not find a sweeter sound. With it's
celeste and separate treble/bass vibrato along with the Leslie it will
produce sounds the B-3 can't approach. Register the same drawbar setting on
both units,except for key click and rumble/hash,crosstalk they are very
nearly indistinguishable.
  The '66 tonewheels feed a clipper amp,then to dividers of a non
conventional design. Very stable system/waveforms.

Hi Harold.
The X-66  only has twelve tone wheels and the signal coming from these
twelve tone wheels pass through octave divider circuitry in order to
produce  the rest of the flute tones for the various drawbar footages.
The octave dividers would produce a distorted sounding waveform such as
a sawtooth wave or a square wave and then these raw waveforms would pass
through steep low pass filters in order to minimise the distortion
harmonics and thus result in a simulated approximation of a sine wave
similar to how  a lot of the electronic organs produce the flute tones. 
 
You can hear the difference between the normal B3 type tone wheel sine
wave and the simulated sine wave of the X-66 , the Conn and other
electronic organs.
 
Three years ago my friend and I visited an organist ( now deceased )
who  had  an X-66 connected to a Leslie 720 , an L-100 organ and a
Hammond Suzuki XM-1 module.
The simulated sine wave flute sounds of the X-66 sounded synthetic like
that of electronic organs  and definitely not as good as the real B3 ,
L-100  etc  tone wheel  sine wave flute  sounds.
 
The organist loved the old style theatre organ style and his favourite
organist was Lenny Dee. 
The sounds and the multi effect features of the X-66 organ are ideal for
the theatre style organ music as well as the Butlins camping ground
organ music and bingo club organ music, and circus organ music  etc
however the X-66 did not sound as good as the normal tone wheel  organs
for Rock / Heavy Rock / Progressive Rock/ Black Baptist Gospel / Jazz/
Blues etc. 
All the best.

Can anyone explain why the X 66 has the Theater organ type sound

I had an illusion of flutes sounding somewhat like some Conn models  
with Leslie added.
