Tripple limited bench PSU ( digital ) from wall adapter
Cliff Matthews:
When a device connects to a switching adapter, its negative supply rail can be adversely affected by the mains connected Y-cap. An issue more serious (IMO), can be found in poorly wound Asian SMPS transformer's where primary and secondary conductors crossover each other (sometimes exiting the bobbin en-route to solder terminals) with only a thin enamel to spare human life..
A very hands-on tech in CZ (DiodeGoneWild) shows a dangerous adapter with poor winding's at the end of this video. Enjoy!
