ALPHA 9/9P SERVICE MANUAL
ARCAM ALPHA 9/9P SERVICE MANUAL Issue 1 Serial No. 001 - (Paul Newton July 96) Circuit Description Input/Output Selection The Alpha 9 integrated amplifier has 6 line level inputs and optional phono input selected by use of the motorised `listen' switch, SW201. The use of the 'record' switch SW202 allows recording of one source whilst listening to another. The Processor/Tape 2 switch, SW207, allows tape monitoring of a 3 head tape deck connected to the Processor/Tape 2 sockets. It can also be used to allow input signals to be routed to an external surround decoder for processing before being routed back to the Alpha 9. Tone Control & Preamp Out/Power Amp In The tone control stage on the Alpha 9 is based around a dual op-amp Z2. The first half provides a buffer stage for the tone controls and the second one with its frequency dependent feedback is used as the tone control itself. The output of the tone control then passes through the balance control RV201 and then onto the power amp stages and the preamp out buffer stage formed by Z203. The tone controls and balance pot can be bypassed by use of the 'direct' switch SW205. The Alpha 9 can be driven from an external preamplifier source by moving the internal switch SW206 to disconnect the Alpha 9 preamp stages from the power amp. Power Amplifier The signal from either the Alpha 9 input sockets or an external preamp enters the power amp stage via C12 and R35. Q11, Q16 form a long, tailed pair driven by the current source formed by Q18 and Q19. Q6 is the Class A stage driving the quasi complementary output stage of Q4, Q5, and mosfet's Q1, 2. The Alpha 9 and Alpha 9P utilize an auto bias circuit to maintain the correct quiescent current (IQ). The circuit works by monitoring the voltage across the 0.22 ohm resistors R1, RA1 and comparing it to a voltage derived from the - 44v rail
via R24. Both these voltage are fed into the inputs of comparator Z3. If the voltage across the 0.22 ohm resistors increases the output of the comparator goes high impedance and Q15 is turned off. This causes capacitor C72 to discharge and reduce the bias on the base of Q17 which reduces the IQ. Conversely if the voltage across the 0.22 ohm resistors is low then Q15 is turned on more and C72 charges and increases the bias on Q17 and so increases the IQ. Under signal conditions a low frequency, variable mark/space ratio, waveform can be seen on the collector of transistor Q20 as the bias is being automatically adjusted. Z1 is a d.c. servo used to maintain a low d.c. offset at the speaker outputs. Power Supplies The Alpha 9/9P is powered by a toroidal transformer with 2 sets of secondary windings. The main windings are used to provide +/-44V D.C. after rectification and smoothing by diodes D201-204 inc. reservoir capacitors C201, 202. The second winding is rectified to provide an unregulated supply voltage for the motor driver ics, Z402 (for the volume control) & Z403 (for the listen selector).This unregulated supply is also smoothed and regulated with a simple stabilizer circuit (zener diode D402 and associated components) to provide a stable voltage for the micro controller Z401. Protection/ Mute circuit The protection and mute functions are carried out by Z501. This performs turn on delay, d.c. offset detection and thermal cutout. It also displays the status of the amplifier with the use of a bicolour LED - 'Green' for ready and 'Amber' for when the speakers are disconnected internally because of a fault condition or on initial power up whilst the 5 second switch on delay mute is operating. If the unit suffers a current overload the protection circuit may latch and the unit will not reset until it has been switched off and on again. If the protection is activated by a thermal problem the unit will begin to operate again when it has cooled down. The thermal cut out operating point is set by the thermistor TH501, mounted close to the output device heatsinks. Disc Stage (optional)
ALPHA 9/9P SERVICE MANUAL
The optional phono stage board available for the Alpha 9 provides amplification and RIAA equalization for both moving coil (MC) and moving magnet (MM) cartridges. Transistors Q2-5 and their associated components provide the extra gain required for moving coil cartridges when required Z1 forms a flat response gain stage with the gain set by R3 and R4. R5 and C2 provide a low pass filter used as the high frequency part of the RIAA de-emphasis. The negative feedback loop around IC2, R7, 8, 9, 10 and C3 provides the active low frequency RIAA deemphasis. The pcb mounted switch selects between MM or MC. The board is powered by +/- 15V regulated rails from the main pcb and the +15V rail is then regulated to 6.3V by Q1 and D1, D2 to power the moving coil stage.
Disassembly For Servicing 1. 2. Remove the top cover and front panel. Remove 2 screws securing the sub front to the chassis sides and 3 screws holding the subfront to the chassis base. Remove 3 screws holding the pcb to the chassis. These can be found close to the large heatsink and also near to the mains inlet socket. Remove 5 screws from the rear panel, one at each end and 3 along the bottom edge. Remove the transformer bolt.
3.
4. 5.
The pcb, with the rear panel, transformer and subfront attached, can now be pulled backwards out of the unit.
