I've found that on later units with the square rods, it sometimes helps to arch the rod slightly as you re-insert it. Works with 122 style 4H kits and 147 style 26 kits. The scanner is used in the organ as a single-pole 16-throw rotary switch. This website uses popups to improve viewing, which are visible while the mouse is hovered over the item. With the diffuser absent, the distance of the apparent sound source from the rotation center varies inversely with frequency.

Like an acoustic instrument, a Leslie's tone is uniquely defined by its cabinet design and construction, the amplifier, crossover and speakers used, and the motors—not merely by the spinning of rotors. The Beatles used a Leslie throughout the sessions for in 1966. It does not work on the lower manual, or with any other preset down. The service manual states oiling should be performed once a year using Hammond oil, which is available from many organ parts suppliers. The lowest one goes on first.

Includes knob and mounting hardware. I'm sure you'll like having all the notes play again. The middle compartment behaves as a vented enclosure for the woofer, contains the crossover, both drivers, and motors for both rotating assemblies. Remove the lower left black plastic endblock and make a duplicate of it out of wood. Be careful not to bend the pin that the two brushes contact. It is most commonly associated with the , though it was later used for the and other instruments.

Remove the rearmost manual bolts from under the generator shelf. None of these are particularly easy to fix for most owners. Be sure you understand what this will do before you make any changes! I actually have 'Sounds of Jimmy Smith at the Hammond Organ' published by Edmy Music in 1965. With the Leslie on it's face, remove the lower motor. If you're not strong, use two people to remove and install them. This usually involves replacing the amplifier or else powering the Leslie from an external amplifier. Hey, at least they got the key signature right.

Bob Schleicher disagrees with this step, stating: I don't consider this optional, rather necessary. It was a smaller version of the 900 and 910, and contained a 40 watt treble and 50 watt bass amplifier. Harmonic content adjustment is provided for each manual independently. Six of the wires in this bundle are routed up and immediately below the drawbars, where they breakout of the bundle and are soldered to the drawbar ends. Don't chord in the lower octave, but play a realistic full chord. It is constructed as a multi-plate air-dielectric capacitor with 16 stator poles and one rotor.

The stock setup removes the harmonic available at the 9th drawbar. The registration most often used for this style is 800008888. But a serious listen to the best of the listed recordings in the accompanying discography should be sufficient to addict most of the uninitiated to that sound. If any oiling threads are missing or broken, this is the time to replace or splice them. It is located behind the mixing transformer. Vibrato is the periodic raising and lowering of the pitch, and is thus fundamentally different from tremolo which is a variation in only the loudness of the pitch. To solve this on those models, you can jumper out a resistor on the matching transformer assembly, which is the round metal-enclosed thing mounted on the upper right side of the organ.

Behind the pre-amp lies the tone generator, the heart of the Hammond's sound. Items returned for any reason other than defective merchandise will be subject to a restocking fee of up to 15%. Part number 508-059527 This half-moon shaped switch assembly is used to control the fast Tremolo and slow Chorale speeds of the Leslie speaker that is connected to these products. This is the left-most lug on my A-100's Resistor Panel. That ability is the essence of the fanaticism some have toward the instrument. If it they are, do not try to solder them.

This switch cannot be used to select two Leslie's speakers. There is very little phase shift of frequencies below 200 Hz due to their wavelength, though some phase shift may occur up around the crossover point of 800 Hz. Pull out one of the pedal drawbars two in the center of the organ between the sets of nine manual drawbars and play each pedal. But then, why would you want to? After further experimentation, he decided that splitting the signal into a rotating drum and horn helped accentuate bass and treble frequencies. Thus to hear the percussion effect for every note of a run requires a technique that fully releases the currently pressed key prior to depressing the next one in the run. The likely culprit is a crystalline growth that can occur on the plated and metal composing the scanner housing dendrite formation. After it has been triggered and as long as any upper manual keys remain depressed, no Percussion effect will be heard when additional notes are depressed.

Remove the two bolts which secure the drawbar base. After Hammond went out of business in 1986, a former engineer re-established Electro Music, licensing the name from Noel Crabbe, who had acquired the rights to Hammond. The Hammond - starting to rumble - a full-hand slowly ascending glissando - the expression pedal floored - feet pumping furiously - now the Hammond is a full-throated roar - the Leslie a screaming dervish - eyes closed - arms extended - clinching a two-handed altered dominant chord on both manuals. There are a large variety of kits available. Mitchell was so impressed that he tried to patent the speaker, but discovered that he could not. A smaller, more portable version of the 760 is the 820. The audible effect of this is that there is a chirp or ping at the attack of the note.

For modifications to the amp to allow two speed operation, consult a qualified technician. When Percussion is enabled, one of the harmonic busbar contacts from each key is used to trigger the Percussion amplifier. This is normal in all organs of this type and is considered a serious drawback to professional players. If the rod is damaged, replace it. The 122 and and 142 have a balanced amplifier input while the 147 and 145 have an un-balanced input. This switch assembly mounts to the front rail via the two thumbscrews provided and can easily be removed for transportation purposes.
