i have been using it and it’s been fine
but it buzzes now
and also cuts out if you draw more than low power
note
THIS IS NOT THE POWER SUPPLY I FIXED BEFORE it’s different
anyway it’s rated for 10A but is dying being asked for intermittent 6.5
and nothing is obviously hot
so yeah
what’s it likely to be? power transistors?
@moira The buzzing is probably coil whine in the transformer, from some subharmonic of the switching frequency that happens to be in the audible range.
It's possible there's a bad capacitor somewhere, like in the feedback for the controller, or if the power transistors have a snubber circuit.
@toroidalcore it seemed too low pitch for transformer whine but I didn't think about lower harmonics so maybe that's it
capacitors are easy to check, at least. ^_^
(this is not the same model as the one with the splody cap and the values are all different so ... sure hope I have some lol)
thanks ^_^
@moira @toroidalcore Is it around 60hz?
Im wondering if a PPTC has gone bad and is triggering earlier than is specced.

What's it to you?
