Hello fellow DIYers,
A friend dropped off a DIY DAC based on stuffed PCB he purchased off of eBay, see attached picture. Unfortunately the DAC has developed a defect, one channel (left) drops out and distorts quite badly, which is why he asked me to repair it.
I looked it over, checked voltages etc. swapped out the opamps just to be sure, but the defect persists.
Currently I’m looking for a schematic, as without that it will take me hours to draw it up from the PCB. So if anyone has more info I’d appreciate hearing from you, thanks!
