typical tuned and untuned tone generators.
In case any generator frequency is weak 01absent. refer to "Practical Service Sugges-
tions" for the procedure to be used in
locating and correcting the trouble
1-5. M ANUALS. - Musical frequencies from thetone generator go through the manual cable
to terminal strips OIl the two manuals and
from them to the key contact springs
Under each key arc a number of contact
springs (for rho fundamental and harmonicsof that key) which contact an equal number
of busters when the key is pressed. All
contact springs and busbars have preciousmetal contact surfaces 10 avoid corrosion,
and the manuals are sealed to exclude dust
so far ns possible. In case a contact becomes
dirty in spite 0 1 " these precautions, a busbarshifter is provided in each manual to slide
the busbars cndwise and thus provide a
fresh contact surface. (See paragraph 4-3b)
looking under the lower manual 011 the
left hand end (front view) a black woodend block will be observed. One half inch
from the front of this block is a drilled hole.Within this drilling is a small metal tongue
with a punched hole. Using either long nosepliers ora hook, this tongue can be moved
ill and out and it ill turn moves the busbars.
The upper mnnua! shifter is in a similarplace and access to it is from the rear or Lhe
console
The key contacts art: connected through
resistancewirestothelllJnuallerminal
strips. 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 ofthat particular key. The blank spaces
indicate that no key contact is used, inas-
much 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 thisrow have contacts connected to ground
through resistance wires.
The busbars o r eacf mauual.vach onecarrying a certain harmonic, arc wired to
the appropriate harmonic drawbars for
that manual through the "Drawbars" tao

SECTION II
THEORY OF OPERATION
2-1. GENERAl. - This section contains circuit
descriptions of the amplifier chassis, and
the percussion altacluncuts. There arcthree amplifier assemblies in the L-J 00
series instruments. On the upper shelf as
viewed from the rear, to the left is the
vibrato amplifier, towards the center thepreamplifier and percussion amplifier.
while the reverberation and power amplifier
is located on the lower shelf
2-2. PREAMPLIFIERS (See Figure 5-1). - The pre-
amplifier (YO receives all signals impressed
on the matching transformer secondary,which originate by use of the draw bars or
preset labs. Should any percussion tab bein llsc,a portionofthc second, third or
bout harmonics or the upper manual will
also appear In the inpul circuit of the per-
cussion amplifier which will bc discussed
further on
2-3. V IBR A TO PHA SE SHIFT A M PL IF IE R (See
Figures5-1 through 5-4). - The vibrator
system varies the frequency otthe tonesby continuously shifting their phase.
Circuit components include three series-
connected vacuum tube phase shifter stages
(V2A, V2B, and V3A), associated saturablereactors (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
(approx. 6.8 CPS). With either the normalor small vibrato tab ill use, this oscillatorimpresses its signal on V4, a cathode fol-
lower and isolation stage. Positive pulses
now appear on the grid of driver tube V5
The plate circuit of this tube is in serieswith three saturable reactors located in the
plate and cathode circuits of the phase shift
stages. lrrespective of which vibrato stop is
used, the rate remains constant, but the
degree of vibrato is determined by the
amplitude of the positive pulse on thedriver tube.
The continuous phase shift is accomplishedby using 180· out-of-phase signals from the
plate and cathode of each shifter stage and
controlling them with the saturable reactors.
Plate and cathode resistors arc of equalvalue and consequently signals arc equal in
amplitude in each plate and cathode circuit.
The saturable reactors serve as a means ofproviding a varying composite of signals
from both plate and cathode of each stage,
ranging from virtually full cathode signal to
full plate signal
The driver tube plate current varies from
about .Sma to Sma. at vibrato rate. This
current varies the degree of saturation inthe reactor cores and results in a smoothly
varying impedance.
At minimum driver current (when the
voltage feeding driver tube V5 is negative
and driver tube is nearly cut off) the
reactor impedances are maximum and are
large compared to the 15000 ohm plate.circuit series resistors RI04, RIIO, Rl15
Therefore, under this condition most signalwill emanate From the plate. (The reactors
being virtually short circuited by the platecircuit series resistors) and phase shift will
be maximum approaching 180' - sinceplate voltage is 180· out of phase with grid
voltage.
At maximum driver current (when voltage
feeding driver tube V5 is positive und driver
tube is conducting maximum current) the
reactors arc saturated and their impedanceis a minimum <small compared to the 15000
ohm plate circuit series resistors R I04,
RIIO,RI15. Therefore, most signal will
emanate from the cathode (the saturated
and low impedance reactors virtually short
circuit the plate circuit series resistors) and
phase shift will be a minimum - approach-
ing O· - since cathode voltage is in phase
with input grid voltage
Between these extremes, the phase variessmoothly under control of the saturable
reactors.
The continuous change in phase is cqui-

(See Figure 5-5).
2-8. 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 trans-
formers is located a field-effect transistor
These gates 0300 and Q303, are fed alter-
nating pulses from a bistable multivibratorwhich 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 channelinoperative. 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
swell pedal. The multivibrator whichsupplies the keying pulse for these two
gates does not run continually, but rather
is turned off and on each lime a key is
depressedoo the uppur manual. The multi-
vibrator consists of 0305 and 0306. The
multlvfbrator rate varies with the applied
base voltage. This voltage is applied throughthe "Mode Switch" and R684 and R685
0304 provides tho necessary switch pulse
to start thcmultivibrator
NOTEwhenever the reiteration is used,
it completely bypasses the percus-sion section of the AO-42 amplifier
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 amplifiedsignals are then routed inlo the regular
Hammond percussion system at the col-
Icctorof0201. With the "Mode Switch"in the "Normal" position all percussion
voices sound as normal; til at is, they have
no vibrato.
NOTE
To obtain the following vibrato
effects it will be necessary to de-
press one Or both of the VIBRATO
tabs
With the "Mode Switch" in the "Delayed
Vibrato" position, a portion of the percus-sion 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 theirrespective collectors assume the supplypotential + 12V. ·illis + I'lV. from the
collector of Q309 is now applied to the
base 03l 0, thereby placing 031 0 and 0311inastateofconduction.With0311 now
conducting, C633 is placed across the
emitter resistor of 0312. This materially
increases rhe gain ofthis stagc, and as thepercussion is dying away, feeds this ampli-ned 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 Phase-Shift amplifier. All voices so routed [JOW
appear with a vibrato tail-off.

2-9. FREQUENCY DIVIDER - When using the
"Chime"vuicc, it is necessary ro create n
1-1/4 harmonic for the proper reproductionor the "Chime" tone. This is accomplished
by routing the 5th harmonic into an ampli-
fier 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 output of this second
frequency divider is then routed back to
the "Selector Switch", and is used as one
of the harmonics ill the 'Chime" voice.
NOTE
2-10. CYMBAL AND BRUSH - The "Cymbal-
Brush" switch when in the "off" position
disables the keying functions necessary to
produce the "Brush=effect. With the
"Cymbal-Brush" switch in anyone of the"on" positiuns, the 8th harmonic of the
lower manual is disabled and this harmonicbusbar is used for keying the "Brush" effect
TIle pedal signal (keying] contact is used toactivate the "Cymbal't effect each umc u
pcdnl is depressed.
2-1t. BRUSH KEYING - With the "Cymbal-Brush"
switch in any of the ON positions, the base
of 0322 is routed IlOW to the 8th harmonic
busbar in the lower manual. Anytime a keyis depressed, the base voltage of this tran-
sistor is routed to ground, and this stage
stops conducting. The attendant rise in
collector voltage is impressed on one plate
of C608. The other plate of C608 respondsby driving excess electrons off to ground
through resistor K624. The resultant posi-
tivc 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 noiseis now tuned in the collector circuit and
fed to the "Cymbal and Brush" amplifier
which consists of Q325 and 0326

2-13. BRUSH AND CYMBAL 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 ampli-
fier. The wiper oftho overall level control(RG02) now feeds into the AO-43 ampfi-
flcr through R601 and C318 to Pin 7 ofVS. 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 onthe organ.

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 amplifierIn most respects this is a conventional
amplifier circuit, and the schematic diu-
grams, Figures 5-1 through 5-4, will
enable the service man to locate the
trouble.
4-18. KEY DO ES NO T PLAY OR HARMON IC
IS M IS S ING . - This may mean a dirty key
coruact;a broken connection, or a dead
note in the generator. The steps below
will serve to isolate the trouble.
a. Ordinarily only one of the several frequen-
cies used 011 the key will be missing. This
can be determined by holding the key and
operating each drawbar for that manual,
observing on which drawbar the key failsto play. Reference to the manual wiring
chart, Figure 1-7,will tell which fre-quency number is missing.
b. Sec whether the same frequency is miss-
ing 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 frc-
quency. If it is missing on one key but
not on others, a key contact is probably
dirty. In SOllU: cases it may be clearedby striking the key 15 or 20 times in arapid staccato manner to loosen the dirt
If this procedure is not effective, adjust-
mont 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 ofone 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
manualsv check the manual-to-generator
cable or the generator itself.
e. The output of any single frequency onthe 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 generatoris all right, the note will play loudly.
CAUTION
Neve r test the tone generator
with an outside source of current
such as a continuity meter, as
serious damage may result to
the sensitive filter transformers
and permanent magnets. By the
above method, all necessary tests
of the tone generator may be
made with the current supplied
by the generator itself.
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 tocheck these parts. Disconnect. the con-
denser 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
turning, the coil is defective, or themagnet 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 (withthe exception of' u Few wheels which
are alone). Of the 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
remove the dampening pad under thegenerator (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 di-
rectly 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 coilnecessi-
tatcs dismantling the entire generator.
It is possible, although unlikely, that themagnet may have become loose andmoved so far from the wheel as to make
the note inaudible. It may be adjusted
as described in the following paragraph.
