Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
There is only one signal wire connecting the first boards... -
Board: DA0X9QMB8E0
Board was water damaged un 3 resistors are dead.
Does anyone know the values of the resistors? (see photo)... -
