Very good, probably worth repairing (in my opinion) as those PSUs and that Thales kit are not cheap. Curious as to whether that is a transformer or a common mode choke. Some supplies have a link to isolate case from common 0V, but yours may well have issues in that area (as you discovered).
Ralph, it could very well be a choke. The board was labeled L1 I believe, unlike T1 (T for transformers). I know you know this stuff already though. In my research finding either stacked vertically with a ferrite core was extremely uncommon. The only thing I could come close to was a transformer sold out of China. If I'm not mistaken SMPS transformers and choke are made or built specific to the application. So I'm not sure I'll find exactly what I need from a typical supplier (mouser, digikey, ect). Thales Portable ILS Receivers (PIRs) are definitely not cheap. That being said, the power supplies are way overpriced IMO.
@@HavingFunRepairs Good luck. If you had all the time in the world, you may be able to reverse engineer that part of the circuit to determine whether more likely to be a choke or transformer, but yes, finding a substitute may lead to a dead-end.
Hi, are you interested in recycling DC power supplies at low prices? I have a lot of DC power supplies with damaged packaging but no place to dispose of them.
Great video my friend 💯💯👍
Thanks for watching

@@Wendy_Peng I do not have interest.
