[quote author="laitue5"][quote author="clintrubber"]Same looks as the PSU-PCB of lots of cheap DVD-players... [/quote]
Exact! It looks like the PSU I saw a few days ago in a dead DVD player.[/quote]
When the dirty deeds (experiments & tests) are done then DVD-players like that are not seldom thrown into the bin here at work, uncovered & all. Hadn't realized these wrecks had still such a valuable UA-supply on board :sad:
But serious, switched supplies & audio can of course work together, but I must admit I was surprised to see it here in that UA-box.
Cheap practices or a wake-up call for us overengineering snobbist SMD-hating progress-fearing classA-powerwasting DIY-ers ? :roll:
