Hi Guys,
I have a M-Audio Black Box that has some odd problem in the 5v circuit after the 7805 on the main board (SCH File X33 – CB15-065X4)
Somewhere after the 7805 the positive out is bleeding to ground (3ohm).
I have checked the caps C3, C4, C77 & C76 and the resistor R56, all seem fine.
And for the life of me I can’t find out where the circuit goes after C4, and I have no idea whatsoever how it is getting to J6 & J21, but it is & I can see no trace at all leading there...
Anyone got any ideas or a schematic?
Many Thanks
Nick
