hi guys
i have this amp is a sonido mask 1500.1
is the same board of many amps like memphis, mtx etc...
the problem was the caps blows, and a diode of regulator 5v was damaged.
i replace that and now the amps works good. the rail voltage is fine
but i have 200mv dc offset and the board dont have potentiometer to adjust to zero like the other same boards
any idea?
thanks!

Is that with or without a subwoofer connected?
hi sir babin
without subwoofer i measure 600mv
and with subwoofer 200mV
but is working
I think it's OK. These amplifiers don't have DC feedback so they can have a lot of offset, especially without a load connected.
understood
so is working fine ?
