Instruments required:
1) Sinusoidal signal generator, 4) Variac 0-250Vac,
2) Dual trace scope, with probe, 5) Resistive load 4 Ω 800W,
3) Digital multimeter, 6) Pink noise from the GM “AUDIO CD”.
P.S: Isolate the oscilloscope from earth and adjust the two traces on center of screen in GND
position.
Par. 1: visual check
-Make a visual check if the amplifier is perfectly done and especially verify:
a) the right value of fuses 8A 250V *4PCS
b) the right earth main connection on rear surface of front panel.
c) the insulation between the heat-sink and the case of TR1-24, IC3-5-then,
-Set the VOLUME control full clockwise.
Par. 2: connections
-Switch off the amplifier module,
-Set the ENCODER pot. on preset “NORMAL”.
-Connect the mains of amplifier module to VARIAC and set it at zero AC voltage.
-Connect the signal generator to Line Input (XLR socket) and set it at 100Hz /0dBu,.
-Connect the scope CH1 probe to amplifier low output and CH2 probe to amplifier high output-
Par. 3: Initial test
-Increase slowly the VARIAC voltage up to the nominal value (230Vac).
-Check the transformer sec. voltages with multimeter, (without signal on input):
F1-F2: 54V ±1.5Vac
F3-F4: 106V ±2Vac
-Check the +/-15Vdc supply on relative voltage regulator outputs (IC3 & IC4 devices).
-Switch ON the signal generator and verify that the output signals must be symmetrical referring
to GND, without detectable distortion and oscillation.
-Check that the low amplifier power output signal is39.5V~41V;
--Check of SIGNAL led function, moving the volume potentiometer of amplifier;
when the output signal is <0.5Vpeak the led must be OFF,
when the output signal is > 0.5Vpeak, the led mustbe GREEN lighted.
-Then, rotate the volume potentiometer knob full clockwise
Par. 4: BOOSTER check of LOW Amplifier
-Connect alternatively the CH2 probe tip of scope on D2 cathode and D3 anode and
verify the following conditions:
when the output signal is <18Vrms the ±VCC1 voltage must remain linear at 36V,
when the output signal is > 18Vrms the ±VCC1 voltage must follow the output signal wave with
6Vdc offset, as shown in the following picture

TESTING PROCEDURE
-Switch ON the LOW amplifier output to 4Ωload resistor and repeat the above booster check
verifying more or less the same ± VCC1 conditions and verify that the signal must be
symmetrical refer to GND, without detectable distortion and oscillation.
Increase the VOLUME pot. until a signal clipping.
Switch OFF the LOW amplifier out. to 4Ω load resistor
Par. 5: COMPRESSOR check of LOW amplifier
-Increase the input signal of 10 dB and check the out. signal to remain constant at 45Vpeak and
if the Signal/Comp. led has changed the lighted colour, from GREEN to RED.
Par. 6: PTC function check on Heatsink
-Heat the PTC temperature sensor with a welder heated tip, in touch with its body, to verify this
protection works properly reducing the amplifier out. signal to few volts on time.
P.S. The check must be done with PTC, placed into heat-sink hole and silicon grease on.
Par. 7: Idle current setting of LOW amplifier
-Decrease to zero the signal generator, then, adjust VR1 trimmer to have a 3mV ±0,5mVdc
voltage drop across R24& R26power resistors.
-
Part .8: Burn-in test
1. Connect the pink noisesignal from CD player with the line input of speaker module.
2. Connect 4ohm 500W load resistor with the bass output.
3. Put band switch to the position 1, and then turn on the power switch of speaker module.
4. Adjust the pink noise level from CD playeruntilSIGNAL/LIMIT indicators (red, green) sparkle.
5. Put the speakermodule vertical and take the burn-in test for 3hours.
Part .9: Final inspection
1. Check the electronic performance of the tested unit completely.
