Theory of function The input signal is connected to the balanced amplifier and gain switch U1, U201 on the IN2GTD-board. The signal is then passing the gain control on the front panel, going to amplifier U2 (IN2GTD). The gain in this amplifier can be reduced by opto resistor U5 to prevent clipping in the output amplifier. Limiter Q1, Q2 together with the phase linear lowpassfilter U3, U4 limits the slewrate of the signal going to the output amplifier A20TDL, preventing intermodulation in this amplifier if signals of too high frequencies are presented on the input terminal. The output amplifier A20TDL works as an ordinary power amplifier with the difference that the collector voltage to the output transistors is supplied from the switch mode amplifier A20TDH. The base voltage of the output transistors Q26-Q28, Q31-Q33 (A20TDL) is sensed by voltage divider R36-R38 and is then sent to the adjustable limiter U3, U4 on the IN2GTD-board, before it reaches the input of the switch mode amplifier (A20TDH) . Limit level is set by the MLS switches S1 and S2. This limiter is used to limit the maximum output voltage from the amplifier. These switches also change the sensitivity for the led bars on the front panel. The amplifier U1 (U2) on the A20TDH-board makes sure that the output signal on terminal CP4 (CP8) is a copy of the input signal on terminal CP12, by giving correct control voltage to pulse width modulator U3. U3 compares this voltage with an 614kHz triangular wave giving a pulse width modulated output signal from Q1 (Q7) which is filtered by L1, C1 (L4, C10). The gain from the base of the output transistors on the A20TDL-board to the output of the A20TDH-board is equal to one. VR1 (VR2) is used to add a DC-offset on the input of U1 (U2) giving +7,5V (CP4) -7,5V (CP8) relative output of the LF-amplifier (CP6A), which is the same as collector-emitter voltage for the output transistors Q26-Q28 and Q31-Q33. Repairing instructions REQUIRED MEASUREMENT EQUIPMENT: -Audio generator -Dummy load, 16 ohm -AC-voltmeter/THD-meter -2 digital voltmeters -Two channel oscilloscope for audio 1. Without changing any fuses check the power supply +155V, -155V, +16V, -16V and +45V. If these aren't OK go to the service manual for the power supply. (The +45V voltage is not regulated and can vary between 30 and 60V depending on the load of the power supply.) If all fuses are OK, follow the signal from input to output, and repair in normal way. The best way is to place the amplifier on the front handles, loosen the rear panel, and mount it back on distances (delivered with this manual) to make it possible to measure. If there is a fault in the power amplifier stage do as follows: 3:1 3:2 3:3 3:4 3:5 3:6 3:7 Turn VR1, VR2 (A20TDH) and VR3 (SP80FB) counter clockwise. Short-circuit R38 on A20TDL-board. Disconnect cables from CP23 and CP24 (A20TDL) (Q26-Q28 and Q31-Q33 collectors). Replace broken fuses. (only for the channel you repair) Connect DC-voltmeter (200V) to the positive (negative) rail voltage. Connect another DC-voltmeter (20V) to the cable disconnected from CP23 (CP24). Turn VR3 (SP80FB) slowly clockwise, and watch the voltmeters. Rail voltage should increase rapidly, "collector voltage" should read 0. After turning VR3 maximum 30, rail voltage should be 155V.

If the rail voltage is zero or very low, check Q1, D1A, D1B (Q7, D5A, D5B) (shorted) on the A20TDHboard. If Q1 (Q7) is broken, also replace R3 (R16) and D2 (D6). If the rail voltage is OK, turn VR1 (VR2) on the A20TDH-board slowly maximum clockwise. Voltage measured on the disconnected collector cable should stop at about 7,5V. If OK turn VR1 (VR2) (A20TDH) and TP3 (SP80FB) counter clockwise.

Repeat from 3:5 for the negative side. Reconnect cable to CP23 (Q26-Q28 collector). Connect dummy load 16 ohm to output, and connect an oscilloscope (10V/div) across the load. Slowly turn VR3 (SP80FB) for 155V (-155V) rail voltage. Slowly turn VR1 (VR2) (A20TDH) clockwise and look at the oscilloscope. There should be no DC on the oscilloscope. If there is DC (>1V) repair the positive (negative) output section on the A20TDL-board. Turn back VR1 (VR2) (A20TDH) and VR3 (SP80FB), and disconnect the cable from CP23 (Q26-Q28 collector). Reconnect cable to CP24 (Q31-Q33 collector) and repeat from 3:11 for the negative side. Reconnect cables to CP23 and CP24. Turn VR3 for 155V rail voltage. Turn VR1 clockwise, no DC on the oscilloscope. Then slowly turn VR2 clockwise. There can be some oscillation with VR2 in middle position, but it will stop at further turning. Connect 1kHz sine wave to the input of the amplifier. Adjust gain until there is signal on the output. It should be a 7V PK sine wave with no distortion. Disconnect short circuit from R38, and the amplifier will work.

Theory of function SP80FA-board: AC-power is coming in to terminal P1, passing interference filter L1, L2 and then reaching RE1 and R5. In some variants the on-off switch is located directly after terminal P1, in other variants it is connected to CP5-CP7, controlling the soft start relay RE1. When the on-off switch turns in position CP5-CP6, soft start resistor R5 gives power to mains rectifier D1. The voltage is rectified by D1 and filtered by C8, C9 and C1, C2 (SP80FB). This gives 310V DC to the transformer. SP80FB-board: Current generator R17, D4, Q5, R16, R10 charge C9 until D3 conduct at 15V. Q8 work as under voltage protection for the +15V voltage by turning U1:3 to 5V if U1:15 drops below 14V. When U1:2 (under voltage protect) reach 3V soft start capacitor C10 (U1:8) is released, witch slowly increase the pulse width of U1:12. The PWM-controller U1:12 controls the switch Q1-Q3 to give the correct output voltage at terminal CP17, CP19 (SP80FA). When the switch Q1-Q3 is closed, current flows trough transformer, storing energy. Because of the voltage polarity, diode D3, D4 (SP80FA) are reverse-biased, thus no voltage present at the load. When the switch is open, the transformer reverses polarity because of the collapsing magnetic field, forward-biasing diode D3, D4 and inducing a current flow into the capacitors C12, C14 (SP80FA). If U1:3 (over voltage protect) goes above 3V the pulses on pin 12 stops immediately. This occurs if the main voltage is too high, or the voltage across snubber capacitor C5 is too high. The reversed voltage is sensed by a winding in the transformer and rectified by diode D8. The PWM-controller adjust the ontime of the switch, by comparing the voltage across C14 (U1:17) with an internal reference (U1:16), to give the right rail voltage across the capacitors C12, C14 (SP80FA). The voltage can be adjusted by potentiometer VR2. The maximum current in the transformer is sensed over the resistor R6-R8. The voltage across R6-R8 is compared (U1:6) with a reference-voltage, set by VR3, witch make it possible to adjust the maximum output power from the power supply. Normally VR3 is in maximum position, but if something has to be repaired in the amplifier, VR3 is used for "slow starting" the amplifier. SP80FA-board: Immediately when Q1-Q3 (SP80FB) turn on, D2 rectify the pulse from the transformer (CP11, CP12). The DC voltage across C7 activates RE1 witch short soft start resistor R5. To turn off the amplifier the on-off switch is set in position CP6-CP7. This disconnects R5, and open RE1, turning the amplifier off. Repairing instructions REQUIRED MEASUREMENT EQUIPMENT: -Audio generator -Dummy load, 16 ohm -Digital voltmeter -Variac 0-280V, 6A -50Mhz oscilloscope, ex. Tek 2225 with 100x probe ex. Tek P6009 -Isolation transformer for the mains, 1:1 1) 2) 3) 4) Turn VR3 (SP80FB) fully counter clockwise. Change FU1 (SP80FA). Increase the main voltage slowly by the variac. Measure the voltage across C8 and C9 (SP80FA). a) No voltage: -change R5 (SP80FA). b) The current increases quickly: -check D1 (SP80FA).

-check Q1, Q2, Q3 (SP80FB). It is now possible to increase the voltage across C8 and C9 (SP80FA) to approx. 300V without current inrush. Measure across Q1 (SP80FB) collector and emitter with an oscilloscope. This oscilloscope should be connected to mains power with an isolation transformer. Turn VR3 slowly clockwise until a pulse is visible on the scope. The frequency is approx. 27 kHz (see figure1). If the graph is seen, go to item 9). 8) If only narrow spikes is seen, check the following components. a) D3, D4 (SP80FA) or the output circuits. b) D1, C5, R1 (SP80FA) -makes U1 go into over voltage protection. c) U1 -the output will remain low all the time. 9) Turn VR3 fully clockwise: a) Check the output voltage on C12, C14 (SP80FA). Adjust with VR2. b) Check the soft start circuit by turning the main switch on and off and look at the oscilloscope. c) Increase the power by applying an audio signal to the amplifier and turn up the gain controls. -The pulse width will increase. d) Check the over/ under voltage protection circuits by turning the variac up to 280 VAC and down to 130 VAC. (No load) 7)
