Need help finding power supply

Long story short, the transformer on my power supply got damaged and I am in the market for a new one. I really need help finding someone or a company that sells these. Any leads would be immensely appreciated.

 

Insufficient information.

Output voltage(s)? Output current? Overall wattage? Input voltage?

 

What makes you think the transformer is faulty?
Do the reservoir capacitors have flat tops?

The transformer runs at high frequency so will have few turns. You may be able to rewind.

 

If the transformer has indeed failed, it will be very specific to that particular power supply. If so, the only solution if the manufacturer will not supply a replacement which they probably won't, will be to re-wind it.
Have you checked to see if the switching transistor is working?

 

You're far more likely to find the entire power board OR the entire product as salvage and pull the power board or just transformer (since the transformer itself is an unlikely failure point) out of it.

I second duke37's question, what led to the conclusion that the transformer failed, how did it happen?

If all else fails, you could substitute a different power board with the same voltage and equal or greater current specs, and if it doesn't have the minor (lower current and voltage) power rails then you can take those off the output of the major power rail voltage.

If it is not required to have the replacement PSU be contained within the original product then it becomes even easier to source a PSU for a tethered-brick arrangement where the replacement PSU is external to the product.

 

Long story too short.
To what does the power supply belong to?
Those transformers very rarely fail. Check that switching transistor / IC mounted on the heat sink between L2 and C43.

 

Lambda is one of the largest power supply manufacturers in the world. That transformer is a fully custom design, prototyped and verified in-house and then shopped out to a low cost, high-volume manufacturer for production. Long story short - you cannot buy a replacement transformer.

As above, the odds that the transformer has failed are very low. Everything on the top side looks OK. Close-up, in-focus photo of the bottom side - ?
