T O N E G E N E RA T O R. - All tones or the organ originate as electrical signals ill tbe tone

generator assembly. It contains 87 tone wheels having various numbers of teeth, with suitable gears for driving them at various speeds from a main shaft extending along the center. Each pair of tone wheels is mounted on a shan and between them is ubakclilegearheldbyacoilspring,fOl"ming a mechanical vibration filter. As the gear is not rigidly attached to the shaft, any pair of wheels which may be slopped accidentally will not interfere with tn e operatiou of the others Adjacent

The manual wiring chart, Figure 1-7, shows how the contacts of each key are connected to the proper frequencies to supply the fundamental and harmonics of that particular key. The blank spaces indicate that no key contact is used, inasmuch as the higher harmonics of these keys art: not required. Since the percussion control circuit is keyed through the 6th harmonic busbar, the blank spaces in this row have contacts connected to ground through resistance wires.

Circuit components include three seriesconnected vacuum tube phase shifter stages (V2A, V2B, and V3A), associated saturable reactors (SRIOl, SR 102, SRI 03), voltage amplifier (V3A), vibrate oscillator (V4A), and driver stages (V4B, Y5) A single low frequency oscillator (V4) provides the rate for the vibrato system

Therefore, under this condition most signal will emanate From the plate.

With the "Mode Switch" in the "Normal", "Vibrato". or "Delayed Vibrato" position, the various pre-voiced percussions are routed to a percussion preamplifier made up of 0314 and Q313. These amplified signals are then routed inlo the regular Hammond percussion system at the colIcctorof0201. With the "Mode Switch" in the "Normal" position all percussion voices sound as normal; til at is, they have


MODE SWITCH- With the "Mode Switch" in any 0 1 " the reiteration positions, the harmonics necessary 10 produce the "Chime", "Guitar",and "Banjo" are all fed into the "Avreiteration channel only, while the "Marimba" and "Xylophone" effects feed harmonics into both the "A" and the "B'tcharmels. This split into the "A" ami "B" channels only occurs with the use of reiteration. without reiteration, all effects are routed into the regular percussion system, The two reiteration channels are identical. You will note that across the secondary windings of the two input transformers is located a field-effect transistor These gates 0300 and Q303, are fed alternating pulses from a bistable multivibrator which supplies alternate pulses to each one of these gates. That is; one is on, while the other is off. These gates shuntthe signal to groun"d,"""therebymaking the channel inoperative. These individual signals are Iurthur amplificd by a one stagc transistor amplifier, 0::;01 for the "Avchannct, an d Q302 for the "B" channel. They arc then mixed together and fed to a common amplifier, 0307, which in turn Feeds this percussion signal to the input side ortne multivibrator swell pedal. whichtwo supplies the The keying pulse for these gates does not run continually, but rather is turned off and on each lime a key is depressedoo the uppur manual. The multivibrator consists of 0305 and 0306. The multlvfbrator rate varies with the applied base voltage. This voltage is applied through the "Mode Switch" and R684 and R685 0304 provides tho necessary switch pulse

With the "Mode Switch"

in

the "Delayed

Vibrato" position, a portion of the percussion signal is taken from the input side of the Expression pedal, and routed to a voltage divider made up or R682anu R681. This weak signal is fed to the base of 0312. T t will be noted that the emitter of this stage is not bypassed and that the output of this stage is relatively low. During keying, after a prcdetcnuined time lag (.5 seconds), the charge on C631 is depleted by 0308 and 0309. With this charge depleted, 0308 and 0309 slop conducting and their respective collectors assume the supply potential + 12V. ·illis + I'lV. from the collector of Q309 is now applied to the base 03l 0, thereby placing 031 0 and 0311 inastateofconduction.With0311 now conducting, C633 is placed across the emitter resistor of 0312. This materially increases rhe gain ofthis stagc, and as the percussion is dying away, feeds this amplined pornon of the fading percussion signal through the "Mode Switch", and R683 to the grid of VI A (Pin 2). There the signal is amplified and fed to the Vibrato PhaseShift amplifier. All voices so routed [JOW appear with a vibrato tail-off. 2-3

This is accomplished by routing the 5th harmonic into an amplifier Illude up of Q315 and Q316. Q317 rectif'ies and Further amplifies this pulse which is then fed to a two-stage frequency divider. made up of Q318, 0319, 0320, and 0321.

The attendant rise in collector voltage is impressed on one plate of C608. The other plate of C608 responds by driving excess electrons off to ground through resistor K624. The resultant positivc voltage is then fed throughD203 to the base of" Q323, the "Brush" gate. To the base of this "Brush" gate is also fed the noise from the noise generator 0324. This noise is now tuned in the collector circuit and fed to the "Cymbal and Brush" amplifier which consists of Q325 and 0326

AMPLIFICATION.-

After being amplified by Q325 and Q326, the "Brush and Cymbal" signals arc routed to a voltage divider consisting of R604, R605, and R606. It is then lapped by the switch and routed to R602 the cverallteve! control This is located on a terminal strip 011 the lower organ shelf, ncar the AO-43 amplifier. The wiper oftho overall level control (RG02) now feeds into the AO-43 ampfiflcr through R601 and C318 to Pin 7 of VS. To enhance the "Brush and Cymbal" effects, a small high frequency speaker is attached to the main amplifier. It is located under the lower right hand end block on the organ. 2-14.

a.ifthegencralormotorisnottumingand the tubes do not light when the switch is in the "on" position, check the power wiring, power switch, line cord, line cord plug, and wall outlet. b. If the generator turns and the tubes light, but no sound can be obtained with all call troIs in playing position, the most likely source of trouble is the amplifier In most respects this is a conventional amplifier circuit, and the schematic diugrams, Figures 5-1 through 5-4, will enable the service man to locate the trouble. 4-1 8.

The output of any single frequency on the tone generator may be checked by pulling out any drawbarand connecting a dip lead from the back end of the drawbar to the generator terminal in question. Sec figure 6 for location of all generator terminals. ll the generator is all right, the note will play loudly.

a. Ordinarily only one of the several frequencies used 011 the key will be missing. This can be determined by holding the key and operating each drawbar for that manual,

f. If it fails to play, try touching the clip to the input side of the filter coil (not the grounded tap) nnd theinput side of the filter condenser {Figure 1-6) in order to check these parts. Disconnect. the condenser to eliminate the possibility of a grounded transformer. if the signal is still missing at the magnet coil terminal, it means that the tone wheel is not

observing on which drawbar the key fails to play. Reference to the manual wiring chart, Figure 1-7, will tell which frequency number is missing. b. Sec whether the same frequency is missing where it is used on other keys of the same manual. The wiring chart will tell with what other key and what other druwbar you should get the same frcquency. If it is missing on one key but not on others, a key contact is probably

turning, the coil is defective, or the magnet is not properly adjusted. g. If the tone wheel is not turning, the frequency of rhe other wheel on the same shaft will also be missing (with the exception of' u Few wheels which are alone). Of th e generator magnet location drawing (Figure 1-5), the two frequencies whose numbers are connected by a dotted line arc on the same shaft. Another way to check the wheel is to

In SOllU: cases it may be cleared by striking the key 15 or 20 times in a rapid staccato manner to loosen the dirt If this procedure is not effective, adjustmont of the busbar shifter for that manual will dear it. (See paragraph 1-5.) This will slide the busbars endwise so they present a dean contact surface. In extreme cases, itmay be necessary to hold down the faulty key while making the adjustment. c. If the frequency is missing on all keys of one manual but not on the other manual, look for a break in the cable connecting one manual to the other. d. If the frequency is missing on both

remove the dampening pad under the generator (it is held by the two long channels which form the generator frame) and feci the wheel with your linger to see if it is turning. Each wheel is located directly behind its magnet. shown in Figure 1-5 h. If the magnet coiJ is detective, the generator must be returned to the factory, as replacement ufa coilnecessitatcs dismantling the entire generator. It is possible, although unlikely, that the magnet may have become loose and moved so far from the wheel as to make the note inaudible. It may be adjusted as described in the following paragraph. 4-5
