Hello all, I'm currently working on a SounDigital 2400.4 EVOX. Would anyone happen to know which output fets are used?
Back story: When powered up, the amp has no power light or rail voltage and smoke comes from a few pins of the SG3525a. When I remove the output card, the amp powers up with a blue light and builds rail voltage with no issue.
So the issue seems to be a short on the output card. All output fets don't appear to be shorted when checking continuity between the gates/drain/source, so I believe the issue may be the irs2052m chips instead. But I'm planning on replacing the fets as well while I'm in there. Thanks in advance
