WLM Organs
Made in Finland in late 70's and early 80's, there were 3 models: TRIP, BEAT, & HIT. The organs used solid state analog tone generation with 12 sub-divided oscillators. They were sold primarily in the european market. There is an excellent Web page with more detailed information and images at:"

TRIP - Combo organ with two 5 octave double manuals.
HIT - Two 49-note manuals and a 13-note pedalboard. 9 drawbars and 7 percussion drawbars for the upper manual, 6 drawbars for the lower manual, 4 drawbars for the pedals. Variable percussion attack and sustain. Pedal attack and sustain. Vibrato. Spring-line reverb. 7 presets. Lightweight (60kg, 132lbs) it folded into a plywood, aluminum edged, road case which also served as a stand, a very elegant design from the pictures of it on the Web page.
BEAT - A home model similar to the HIT that was available in 4 & 5 octave double manual versions, 13 note pedal board, and added a simple rhythm machine and a built-in amplifier and rotating speaker system.

Mechanical Leslie Simulators/Clones

Motion Sound PRO-3
The PRO-3 uses a rotating treble horn and a titanium driver in tandem with a stereo/mono bass rotor simulation signal output through 1/4" front panel jacks. You feed an organ signal to PRO-3's 1/4" mono input, and patch the PRO-3 low frequency output signal to a keyboard amplifier. The PRO-3's rotating horn characteristics are modeled on the Leslie 147.

The PRO-3 dimensions are 6.5" x 20" x 16.5" and it weighs 26 Lbs. The front panel is vertically centered on the left third of the unit front. Two rails run along the bottom from front to back and are designed to straddle the handle of a keyboard amp. The horn compartment is vented so that about 60% of the sound comes through the front and 40% through the rear and sides, simulating a 147 horn with the back off and turned around. The horn amplifier is 30 watts RMS with .3% distortion, and is very loud. For more information see:

A review of the PRO-3 is contained in the Hammond/Leslie FAQ at: et/~bbaker/files/pro3review.html
Motion Sound R3-147
The R3-147 Rack Mount System is effectively a fully sealed and acoustically isolated unit containing a PRO-3 with internal microphones and a 12AX7 tube pre-amp. The extensive front panel gives the user control over treble rotor speed and accel/decel rates, bass rotor simulator speed and accel/decel rates, control of AM and FM components and open/closed bass cabinet simulations in the bass rotor simulator. Left and right microphone controls allow for close/distant mic'ing variations and treble/bass rotor balance controls tailor the mix of high and low frequency sound. Rotor fast/slow/stop can be controlled either via MIDI or through a provided footswitch.

Dynacord DC200
The DC200 is a combo amp with treble and bass rotors packaged in separate enclosures. The treble enclosure is 63cm(25")W x 53cm(21")D x 35cm(14")H. The lower enclosure has the same width and depth and is 79cm(31")h. Stacked height is 114cm(45"). The upper enclosure contains the familiar pair of rotating horns (one is a counter balance only) and is open on all four sides. The lower enclosure contains a 15" speaker firing downward into a rotating drum and open in the front only. The unit is trademarked as the "Spacesound System".

The DC200 uses a 200 watt amplifier with separate volume controls for the treble and bass rotors and a common set of bass and treble knobs.

Dynacord is a German company but most of the components are manufactured in Italy. It is not know if the DC200 was offered to the North American market.

Echolette ME II
This unit appears to be a close relative to or copy of the Dynacord DC200.
Two-box vinyl cabinet; upper a horn system like the PRO-3; lower a drum system, including a small forward-facing horn. Amp included a small mixer, and it looked like the rig could be used for additional instruments independently of the whirly sound. A European manufactured unit, it's not know if it was ever sold in the US.
Apparently this was a speaker-only unit, about 2' tall with treble rotor and a statically mounted bass speaker. A Eurpopean manufactured unit, it's not know if it was ever sold in the US.
