The input pair (Q606,607,618,619,706,707,718,719) are in a  
Darlington configuration to lower input current offset which in turn  
will lower DC offset at the output, as the impedances seen on the  
input nodes are necessarily high for the wide bandwidth required.  
A65/75/75P Plus Circuit Description  
PSU  
The output stage is a simple bipolar darlington (Q614,615,714,715).  
However, the devices used are Darlington devices with integral  
diodes. This means the bias temperature compensation is part of the  
output device enabling smaller number of devices, no extra devices  
on the heatsink (vital for this mechanical layout) and more consistent  
temperature compensation of bias. Also the resistors are also  
integral, saving a large amount of PCB real estate and hand insertion  
cost, while also able to be used as bias set test points and protection  
sensing.  
In order get the output devices to turn fully on and achieve the  
greatest efficiency, an auxiliary rail is formed from a charge pump  
driven by the main AC outputs from the transformer. C304,305 &  
D301,302 charge on alternate cycles. In the other cycle the charge  
on C304,305 is pumped into C310,311 respectively. This creates a  
voltage much greater than the standard rails, but with low regulation  
and high ripple. This is then regulated to 38V via emitter followers  
Q300,302,303,305 from a zener stabilized voltage (D304,305)  
The Pre-amp ±15V supply comes from linear regulators Z300,301.  
Due to the decreased efficiency of this type of output stage over the  
previous bootstrapped Mosfet output, a separate set of rails is  
required for the VAS stage in order to saturate the output transistors.  
The operation of this is outlined in the Power supply section.  
However, these rails are individually regulated for each channel to  
decrease power supply crosstalk.  
The transformer is a dual voltage unit, the required voltage being  
selected by which fuse holder is fitted with the appropriate fuse. If an  
alternative to 115V or 230V is required then a different transformer  
is fitted. The secondary is centre tapped for the main rails, but a  
separate winding is added for the uC supply.  
The protection of the output stage is taken care of by a proprietary IC  
(Z101). This takes care of the switch on delay (R150,C149), DC  
offset (R102,103,C147), Thermal trip (TH100), and safe operating  
area.  
The star ground point SP300 is not a component on the PCB and is  
on the schematic only for layout purposes.  
Pre-amp  
The safe operating area is monitored by a network which  
compensates for the voltage across the output devices, current  
through them, and duration of power (R627,606,625,605,C617 &  
symmetrical associated components) and this is sent to the protection  
IC via (Q605,612,613,616,617,712,713,716,717).  
The direct signal path (line in, tone controls defeated) consists of a  
single op-amp gain stage, buffering the j-fet input multiplexers and  
Tape Monitor and AV switches. The selected input is AC coupled to  
the op-amp, the output is DC to the Pre-out, via a j-fet "pre-mute"  
switch. This switch is controlled by the uC in such a way that when  
ever the output relay changes state signal is removed from the power  
amplifier (A65/75).  
The output of the protection IC is sent to the micro controller (uC) to  
signal the output relay (RLY1) status. Also, for output muting  
purposes, the uC can switch the relay via Q100.  
The MM phono stage (by passable A75 only, SW100) is opamp  
based. The circuit is AC coupled to give RIAA/IEC low frequency  
response. The cartridge is loaded by R100,101,C119,120. The 1kHz  
gain is 56dB, and RIAA eq set by  
Input Selection  
The uC controls the operation of the unit. IR commands are received  
from RX900 on a break-off PCB found on the front panel and fed via  
LK900/LK903 3-way ribbon. On power on/off the current state of  
the pre-amp switching stored in an EEPROM Z906. The input  
switching is 5V logic level and is direct from the uC to the DPDT  
analogue switches in the case of Tape Monitor (Z105), AV  
(Z164,A75 only), Pre-mute (Z171) and Mute Q100. The source  
selector is achieved by 8 way analogue multiplexors (Z102,103) and  
the control signals are decoded from the uC from MUX1,2,3 by  
Z907 which also drives the appropriate front panel LED. The input  
selection is set by the remote control or the rotary encoder on the  
front panel display PCB. Tape monitor and AV mode(A75 only) is  
set by SW900.  
R110,112,111,113,C127,129,128,130.  
Each line input has static protection afforded by the back to back  
diodes (e.g. D101,103), and RF filtering is set by R118,C134 etc.  
The selected input is buffered for Tape output by Z104 set as a  
follower. The output resistor is inside the feedback loop so to keep  
the output impedance low and short protection is catered for.  
C121,122 maintain stability into capacitive loads.  
From the tape monitor switch (Z105) onwards the signal is AC  
coupled (C151,152). From there the signal is fed to the tone controls.  
These consist of two stages: Balance and buffer (Z160), and  
Bass/Treble Z161. The output of this stage is again AC coupled.  
Switch SW162 selects whether the tone adjusted signal or a direct  
signal reaches the gain section. In the A75 Z164 can be used to  
bypass the volume control when AV input is selected. This fixes the  
gain to allow an external AV processor to control the volume setting.  
Volume Control  
The volume control is a motorized manual type, where the signals  
are routed through the 8-way ribbon LK189. The motor drive comes  
from Z905, which is a logic level controllable motor driver. It has its  
own unregulated PSU (D907,C920),and the speed of the volume  
knob is dictated by the REF pin. The circuit (Q900,R905,901,C901)  
allows the speed to vary from just above stall to full as the volume  
control button is depressed on the remote.  
The gain stage (Z163) has a gain of 2.2, and the same low impedance  
output arrangement as the Tape output. The signal from this stage to  
the Pre- amp outputs and the Power amp input is controlled by a  
pre-mute (Z171). This removes thumps and clicks, and in the case of  
the Power amp relay changing state, removes signal so arcing will  
not take place.  
SIM Module  
Power Amplifier  
The connector PL161 (P75 only) allows the fitting of the ARCAM  
SIM module. In order to allow this to operate LK172 & LK173 must  
be removed. This will allow 12V trigger signals to operate the P75.  
The new topology is a high gain voltage feedback design, with a  
bipolar output stage. Its signal path is designed to be fully  
symmetrical, despite not having a symmetrical circuit (symmetrical  
rail to rail). This is achieved with a new dual differential input gain  
block, where the input differential sees a symmetrical active load  
(Q600,601,700,701) before driving the second voltage amplification  
stage (VAS) differential (Q603,604,703,704). This could be  
described as two Wilson mirrors with their bases clamped together.  
The second differential also has an active load of a more traditional  
mirror (Q610,611,710,711), and this gives a push pull signal to the  
input of the output stage, improving on the traditional single ended  
current source of the often called "blameless" topology.  
Headphones  
The Speaker outputs (SK600,700) are connected to the headphone  
socket (SK162) via an 8-way ribbon LK170,171. The output is  
attenuated by a resistor network R161,162,236,237. The Relay drive  
is fed through the headphone socket's switch (HPSW1,2) so that  
when headphones are inserted the speakers are disconnected. Switch  
SW163 allows the separate switching of the second speaker  
terminals on SK600,700.

Hints & tips  
To isolate a fault between pre and power stage remove C602 (left channel) or C702 (right  
channel).  
Always check and re-solder o/p device SAP15N and SAP15P pin connections.  
Replace Z900 IC if software version is below version 3 ( note version 82 is also ok ).  
Make sure R127 is not touching LK130.  
When replacing the top cover with a new top it may be necessary to re-drill the fixing holes.
