SAFETY NOTICE 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 returning the product to the owner after any service 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.

11.Technical Description 1.
AC Line Filter (PSH-83D)
The AC line filter board is comprised of inductor L1 and capacitors C1 – C5, a fuse and voltage selector switch. The line filter prevents noise from the organ leaving through the AC line cord. SW1 is voltage selector switch this allows selection of various line voltages available throughout the world to provide power for the organ. The fuse value is selected depending on the source AC voltage the organ is using. 2.
Power Supply Board (PSH-72B)
This board takes the AC voltage from the secondary of the power transformer PSH-119, rectifies it and makes the DC voltages needed to operate the organ (+5V, +6V, +/-18V). The Regulator U3 provides the +5V for the MGH-91A. Regulator U4 provides the +6V used for the heater of the vacuum tubes on the PAH-72A board.
The +/-18V is used for the amplifier ICs on MXH-35A
board. The regulator U1 a 7818 creates the +18volts and U2 a 7918 creates the –18volts. 3.
Main CPU, Sound generator and DSP Board (MGH-91A)
This board has two CPUs, two VASE3 sound generators a digital signal processor and three D/A converters. The main CPU controls the tone wheel generator and multi-contact keying and the DSP provides the effects, reverb, vibrato, Leslie and tone control. 3-1.
Main CPU
U1 is main CPU (SH7017). This CPU has internal flash ROM.
Update of the system’s program
is from an outside 16M flash ROM U4. New system software is loaded from CompactFlash card “CF card.” The Main CPU also controls the VASE3 generators U37 and U36, U2 the DSP, LCD display and switch scan functions. 3-2.
Sub CPU
U3 is sub CPU (3007). This CPU is a high-speed processor it controls the key scan and tube overdrive circuits. 3-3.
Main Memory
Main software is stored in 16M bit flash memory of U4 (29F160B). U57 and U58 is 1M bit SRAM preset and panel switch data is saved in this pair of chips. These chips are battery backed up by BAT 1.
U5 is 16M bit DRAM this is workspace memory.
3-4. System Reset
U11 is a monitor of the +5v and provides reset to main CPU, when this voltage falls. This circuit is used to switch the power supply of Backup SRAM to a battery (BAT1) simultaneously. 3-5. VASE3 Sound generator U36, U37 is generator LSI. This LSI reads the wave data from ROM (U38) and outputs it to DSP and D/A. The upper drawbar, lower drawbar and percussion sounds are mixed. They are sent to DSP U2. And after being divided into the frequencies of High(HF) and Low(LF), they are sent to MXH-35A. Pedal BASS is a separate channel. 3-6. DSP U2 is a Multi-channel dual serial input port DSP. It has a very hi speed (200MHz) internal clocks and U49 is 1M SRAM.
The first half of the DSP receives upper and lower manual digital tone
wheel signals from the VASE3 generator. It adds chorus, vibrato to the drawbars if selected and then splits the Frequency range in two, HF and LF. The second half of the DSP receives data from the A/D U31 and adds tone control, expression, digital Leslie and reverb if selected to the signal. 3-7. D/A Converters and A/D Converter U32, U33, U34 are 24-bit D/A converters. The output of U32 is the upper, lower and percussion drawbars split into HF and LF these signals will go to the mixer board and then out to the Tube overdrive circuit PAH-72A.
The output of U34 is the Pedals. The output of U33 is the combined
organs output with all effects added split into Left and Right outputs.
All of these signals will go
the mixer board. 3-8. Serial Interface, MIDI U15 (PD71051GU) is a serial interface to U1 main CPU. This interface is for the PEDAL MIDI in. A photo coupler, U51 (PC400v) is used to couple MIDI IN signals into the serial interface U15. There is an additional MIDI IN for an added keyboard to be used for lower manual or other MIDI control of keyboard, it is labeled LM MIDI IN. Photo coupler U50 (PC400v) is used to couple the MIDI IN signals directly into the CPU. The LM MIDI IN is controlled directly from the Main CPU thru port 0. Transistor Q2 is used to buffer the MIDI OUT signals generated through CPU output TxD0. The combination of these circuits allows MIDI merging of the 2 MIDI IN ports. 3-9. LCD (Liquid Crystal Display) Control The main CPU, U1 controls the LCD 4.
(20 character x2 lines).
Draw Bar Interface Board (IFH-18A)
ICs U1, U2 and U3 are analog switches that are used to scan 20 channels of analog data from the
upper, lower and pedal drawbars.
The output of these ICs is fed directly into an A/D port of the
CPU U1 on the MGH-91A board from connector J103. U4 is an analog switch used to scan 4 channels of analog data from pitch wheel, modulation wheel, tone control and overdrive level. This analog data comes from J508 on the SWH-503A board. This data is also fed to the A/D port of the Main CPU on MGH-91A. 5.
Switch boards (SWH-503A, 504A, 505A)
These three boards contain the tab switches and LED indicators and controls for the entire organ. The SWH-503A contains the decoder and LED driver circuits for all of the switches on the XK-3. The SWH-504A and SWH-505A boards are wired to the SWH-503A board and utilize the decoder and LED driver circuits on the SWH-503A. The SWH-503A board sends and receives switch and LED signals to main board (MGH-91A) on connectors J503 and J502 6.
Vibrato Mode Switch VRH-29A
This board is the rotary switch which selects the vibrato / chorus mode of C1-V3.
It Connects to
J105 of MGH-91A. If you need to change the board, first remove the 4 screws holding SWH-503A LED indicator board under the switch assembly.
Then pull out the knob and remove the nut on
the rotary switch’s shaft. The switch assembly will then drop down and out of the control panel. 7.
Vacuum Tube Overdrive Board (PAH-72A)
The Tube overdrive board consists of opamp (U1), dual VCA ICs (U2, U3), Tubes (V1, V2) and a 220V dc power supply circuit (D1-4) and (Q1) for vacuum tubes plate voltage. The signals from MXH-35A enter the board at J301. There are 3 signals HF, LF and Pedal. There are 2 parallel audio paths through tube circuits one is for (HF) high frequency and one is for (LF) low Frequency. The Pedal signal does not pass through the Tube overdrive circuit; it bypasses it and is mixed back in at U1B.
The U3 vca controls gain of overdrive level of the vacuum tubes.
The overdrive gain is controlled by the DC voltage (0-5V) control signal from MGH-91A J120. The U3 output signals are amplified by tubes V1 and V2. The U2 vca attenuates the overdrive signals back to the original input levels. The signal is then mixed with pedal signal at U1B. The signal then leaves the board at J301 and goes to MXH-35A.
The control signal is programmed to rectify
according to an overdrive level by HF OUT-V and LF OUT-V this comes from MGH91A CPU. VR1 (HF) and VR2 (LF) are TRIM. Pots in order to revise volume level of TUBE ON or OFF. Please refer to the TEST & ADJUSTMENT for the adjustment method. The Q2 is transistor is an analog switch, if TUBE AMP ON thru signal is stopped. When TUBE AMP Off then U2 gain turned off by MGH-91A.
CAUTION: The vacuum tube power supply voltage is 220VDC. There is a danger of electrical shock if you touch components in this circuit. Use caution when testing this circuit, damage will occur to the Main board and other ICs If you short the high voltage circuit to other components on the board. Please note the capacitor in the high voltage circuit will maintain a charge beyond 100V even after the power is off for over 1 hour. 8. Mixer Board (MXH-35A) This board is an audio mixer board; it consists of Op Amps, Muting relays, Leslie control transistors, voltage regulators and audio jacks. The six audio signals from MGH-91A enter the board and are conditioned by integrated circuits U1, U2 and U3. U1 and U2 act as no gain low pass filters. They have a cut off frequency at 20kHz this is to filter out the Digital noise.
After
leaving U1 and U2 the HF, LF, and a PEDAL signals are sent to PAH-72A. After being processed by the overdrive board the signals return to the mixer board and are mixed with any signal from the send/ return loop by U4A. The signal is then sent out of the board to the A/D converter on MGH-91A. After the DSP signal processing and D/A conversion The Left and Right audio signals return to the mixer board to U3A and U3B. Op amps U3 provide a cut off frequency of 20kHz or more and boost of frequencies 100Hz or less about 10dB. This signal leaves the board and goes through the dual volume control at J206 and return to U6 and the output is sent to a headphone jack and lineout jacks. The main Rch signal is sent to U5 for the Leslie output it goes to the 11-pin connector through J204. U7 and Q7 control the muting relay at the time of power On/Off. There is a 3 to 5 seconds delay to the relay turning on after the power supply is energized; the turn off time is short. Q3 is power ON transistor for external Leslie. When organ is turned on and Leslie is connected to organ this transistor pulls pin 6 of Leslie 11 pin plug to ground thus turning on Leslie. Transistor Q1 is for Fast speed and Q2 is for slow. These transistors receive control voltage from MGH-91A they pull either pin 7 (Fast) or pin 8 (Slow) of 11 pin plug to ground causing Leslie motors to operate at proper speed. U9 and U10 are voltage regulators they Regulate the + and – 18volts to 15 volts for the op amps on the board. This regulated voltage is also supplied to other boards through J208.
