Great care has been taken in the design and manufacture of this product to assure that no shock hazard exists on any exposed
metal parts. Internal service operations can expose the technician to hazardous line voltages and accidentally cause these
voltages to appear on exposed metal parts during repair or reassembly of product components. To prevent this, work on these
products should only be performed by those who are thoroughly familiar with the precautions necessary when working on this
type of equipment.
To protect the user, it is required that all enclosure parts and safety interlocks be restored to their original condition and the
following tests be performed before returningthe product to the owner after anyservice operation.
Plug the AC line cord directly into a line voltage AC receptacle (do not use an isolation transformer for this test) and turn the
product on. Connect the network (as shown below) in series with all exposed metal parts and a known earth ground such as a
water pipe or conduit. Use an AC Voltmeter of 5,000 ohms per volt or higher sensitivity to measure the voltage drop across the
network. Move the network connection to each exposed metal part (metal chassis, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the voltage drop across the network. Reverse the line plug and repeat the measurements. Any
reading of 4 volts RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning
the product to the user.
SAFETYNOTICE
CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
equipment manufacturer. Discard used batteries according tomanufacturer's instructions.

9. TECHNICAL DESCRIPTION
1. General
This unit corresponds with the Leslie 11-pin Input, the 8-pin Input and the LINE Input.
It has 1 channel (the Rotary Channel only) and two very powerful Amplifiers (220W + 80W).
The Treble Horn Rotor and the Bass Drum Rotor are driven by the respective DC
Servo-Motors, The built-in Tube allows natural distortion/overdrive effects without adding excess
Volume similar to the performance of Leslie models 122 and 147.
The Slow/Fast speeds and Rise/Fall times are user-adjustable.
The PWB’s consist of:
a. Pre-Amp & Tube Drive PWB (PAH-74B)
b. CPU Motor Control PWB (CTH-37A)
c. Power Amplifier & Power Supply PWB (PWH-74C)
d. Motor Driver PWB (LGH-43A)
2. Operation of Each PWB
A. PREAMP & TUBE DRIVE (PAH-74B)
This PWB consists of the Pre-Amp, the Tube Drive section and the Filter section.
The signals, input from the Leslie 11-pin Connector Pin (1), are sent through J303-5
and are mixed with the input of the Line-In Jack JK-3 and the Leslie 8-pin Connector CTH-37A
JK-2 Pin (1), then the gain is adjusted at the Sub-Pre-Amp IC1A and VR1, and are supplied to
the input of the V1 through the Tube ON/OFF switch of the VR1.
The V1 is the circuit for the Tube-Overdrive. With this, the user can set the Overdrive to
the VR1 Drive Level and the VR3 Tube Mode Volume from softer distortion to hard distortion as
required.
The Overdrive can be switched OFF, only by turning the VR1 Drive Lever to the leftmost position, i.e.
“Tube OFF”, which automatically switches ON the direct input to IC1B.
Next, the signals, sent through the Master VR2, can be controlled by the Bass (60Hz), the MID (1.7kHz)
and the Treble (10kHz) by ±10dB Iusing the 3 band Equalizer C2.
Finally, the signals, divided by the HPF and the LPF of the IC3, are sent to the PWH-74C by J302.
Also the signals for the Sub-Woofer (below 125Hz) and those for the Line-Out are sent to the JK4
through the VR8.
B. CPU MOTOR CONTROL (CTH-37A)
This PWB consists of the Voltage Generating circuit for the Motor Control, the CPU circuit for
controlling and the Power IC circuit.
The U1 CY8C24423A is a 1-chip CPU, containing the built-in CPU of the Clock circuit, the
ROM,RAM,
and Analog Interface circuits. This most advanced Controller CPU is operated by the
Power Supply of only +5V. It monitors the Rotation Pulses (J205-1, 2) of the Horn side and the Drum
side Motors, emits the Brake Pulse to the LGH-43A circuit, and automatically controls the Rise Time.
It also monitors the Slow/Fast Control signals received via the Leslie 11-pin and 8-pin and controls the
motor rotation with “Last-Action-Priority” by adding the Foot-Switch operation.
9-1

#3300P
An advanced feature is the Rotation Speed Adjusting-mode. It enters this mode by pressing
the Foot-Switch for 5 seconds or longer at Power ON. By using the LED on the panel, the Rotation
Speed of Slow and Fast is controlled.
Refer to Page 11 of the Owner’s Guide for details.
The function of the U2 is to control the Rise/Fall of the Motor Control Voltage, together
with the constant circuit at the time of VR1,2,3,4 and C51,52.
The TR Q1,3 and the TR Q2,4 are driving circuits to switch ON/OFF +12V and convert the
Slow/Fast signals, sent from the U1,and send to the Adjusting circuit of the U2 Rise/Fall Time.
Finally, the voltage for controlling the speed is put out from the J205-3PIN and 6PIN to the
LGH-43A PWB.
The Power circuit makes +12V and +5V for the U1 from +15V from the PWH-74C by using
the U4 (+12V) and the U3 (+5V).
C. POWER SUPPLY & POWERAMP PWB (PWH-74C)
This PWB consists of the Power Supply, the Power Amp, the Power ON Muting circuit
and the Remote Power ON circuit.
POWER SUPPLY:
TheprimarysideofthePower-TransEPH-123 is designed for easily switching 100V, 120V,
220- 230V, and 230 - 240V by changing the combination of wirings of the Voltage-Select Plug.
There are three lines of ±34V, ±17.5V, +30V secondary side of the transformer.
From these the Power Amp’s power source, ±15V, +24V Motor’s power source are produced.
The devices PSW1, 2, 3, placed between the transformer volume line and the rectifier diodes,
are Poly-Switches and function as fuses.
They reset by re-switching ON after removing the reason for the blown fuse.
They do not require replacement in normal use.
The Part No. RXE-185 corresponds to the 1.6A Time lag or Slow Blow Fuse.
POWER AMP:
The Power-Amp consists of 3 channels: 3-Channel Amp IC U1.
The Treble-side amp. and the Bass-side (BTL motion) function as 1 channel.
The output of the U1 Amp is mixed through R8,9 (0.22 ohm) at the Pin 12,13 and is supplied to
the Horn Driver through the Choke Coil L2, via J102-1. The U1 has a Muting circuit for
preventing a Pop Noise at Power ON and OFF.
The heat-sink is equipped with a DC cooling fan, which detects the temperature by the TH1 Thermistor
and the U6 IC. If the temperature approaches 50 deg C, the DC fan automatically turns and prevents excess
heating of the heat-sink.
REMOTE POWER ON:
The T1 is a Sub-Power-Transformer for the Remote-Power-ON circuit. It is always connected to
the power source, even when the main power is switched OFF. The Power-ON signal of the Leslie
11-pin is connected to the RL3, and, if the terminal goes down to the GND level, the RL3C is switch-
ed ON and = the Power is switched ON, and, if the organ and the 11-pin cable are connected, the
Power Switches on the organ and the Leslie operate simultaneously.

#3300P
D. MOTOR DRIVER PWB (LGH-43A)
The LGH-43A is a DC Servo-Motor-Drive circuit-board and controls the motors at the Speed
Control Terminal (CN3-5) and the Brake Terminal (CN3-9). It also sends the rotation information
by the Rotation Pulse to the CTH-37A from the CN3-1.
The approximate Speed Control Voltages are [0.7VDC] at Slow, and [7.0VDC] at Fast.
Pay particular attention in making the correct connection of the Horn(UP)Connector (5-pin-PINK)
And the Drum (LOW) Connector (5-pin-RED).
If the connection is not correctly made,
the control of Rise Time on the drum side is not possible.
On the PWB, the over-current-protective circuit is built-in, which stops the motor rotation in
case the load on the motor is abnormal, but it will function normally by re-switching the power ON
after removing the excessive load.
