Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"

SECTION 3 ELECTRICAL ADJUSTMENT
Bias Adjustment
Note : The Bias adjustment should be performed only if any of Q108 to Q113 and Q208 to Q213 are replaced. Setting :
B+,REM terminal
set Stabilized Power suppy GND terminal
Procedure : 1. Rotate the variable resistors RV105 and RV205 fully in the clockwise direction to minimize the idling current of the stabilized power supply. 2. The input signal is to be no signal. 3. Set the power voltage to +14.4 V, and turn the remote mode ON (Connect between the REM terminal and B+ terminal). 4. Adjust each of RV105 and RV205 so that the power current of the stabilized power supply is increased in steps of 500 mA for the XM-1502SX and in steps of 600 mA for the XM-1902GX. Adjustment Location : Main board (component side)
