Hi guys
Can anybody please provide me with the schematic
For the audio driver board of a digital design or any
Other compatible audio driver board?
I have problem with two of these boards, one is belongs to
A hifonics and the other for a digital design. But are very
Similar except for some resistors.
Both amps work without the audio driver board install, but are
Going in protection mode when driver board is in circuit.
I have replaced
Ir21844
Q9
Q10
And the 2.7 k resistors by the 2D transistors
On both boards.
Thanks in advance
